There was no way to setup correct repo when AMI is building by --localrpm option, since AMI does not have access to 'version' file, and we don't passed repo URL to the AMI.
So detect optimal repo path when starting build AMI, passes repo URL to the AMI, setup it correctly.
Note: this changes behavor of build_ami.sh/scylla_install_pkg's --repo option.
It was repository URL, but now become .repo/.list file URL.
This is optimal for the distribution which requires 3rdparty packages to install scylla, like CentOS7.
Existing shell scripts which invoking build_ami.sh are need to change in new way, such as our Jenkins jobs.

"Kubernetes is unhappy with our Docker image because we start systemd
under the hood. Fix that by switching to use "supervisord" to manage the
two processes -- "scylla" and "scylla-jmx":
http://blog.kunicki.org/blog/2016/02/12/multiple-entrypoints-in-docker/
While at it, fix up "docker logs" and "docker exec cqlsh" to work
out-of-the-box, and update our documentation to match what we have.
Further work is needed to ensure Scylla production configuration works
as expected and is documented accordingly."

Previously, the Docker image could only be run interactively, which is
not conducive for running clusters. This patch makes the docker image
run in the background (using systemd). This makes the docker workflow
similar to working with virtual machines, i.e. the user launches a
container, and once it is running they can connect to it with
docker exec -it <container_name> bash
and immediately use `cqlsh` to control it.
In addition, the configuration of scylla is done using established
scripts, such as `scylla_dev_mode_setup`, `scylla_cpuset_setup` and
`scylla_io_setup`, whereas previously code from these scripts was
duplicated into the docker startup file.
To specify seeds for making a cluster, use the --seeds command line
argument, e.g.
docker run -d --privileged scylladb/scylla
docker run -d --privileged scylladb/scylla --seeds 172.17.0.2
other options include --developer-mode, --cpuset, --broadcast-address
The --developer-mode option mode is on by default - so that we don't fail users
who just want to play with this.
The Dockerfile entrypoint script was rewritten as a few Python modules.
The move to Python is meritted because:
* Using `sed` to manipulate YAML is fragile
* Lack of proper command line parsing resulted in introducing ad-hoc environment variables
* Shell scripts don't throw exceptions, and it's easy to forget to check exit codes for every single command
I've made an effort to make the entrypoint `go' script very simple and readable.
The goary details are hidden inside the other python modules.

(cherry picked from commit d1d1be4c1a)
Calls like later() and with_gate() may allocate memory, although that is not
very common. This can create a problem in the sense that it will potentially
recurse and bring us back to the allocator during free - which is the very thing
we are trying to avoid with the call to later().
This patch wraps the relevant calls in the reclaimer lock. This do mean that the
allocation may fail if we are under severe pressure - which includes having
exhausted all reserved space - but at least we won't recurse back to the
allocator.
To make sure we do this as early as possible, we just fold both release_requests
and do_release_requests into a single function

(cherry picked from commit fe6a0d97d1)
Issue 1510 describes a scenario in which, under load, we allocate memory within
release_requests() leading to a reentry into an invalid state in our
blocked requests' shared_promise.
This is not easy to trigger since not all allocations will actually get to the
point in which they need a new segment, let alone have that happening during
another allocator call.
Having those kinds of reentry is something we have always sought to avoid with
release_requests(): this is the reason why most of the actual routine is
deferred after a call to later().
However, that is a trick we cannot use for updating the state of the blocked
requests' shared_promise: we can't guarantee when is that going to run, and we
always need a valid shared_promise, in a valid state, waiting for new requests
to hook into.
The solution employed by this patch is to make sure that no allocation
operations whatsoever happen during the initial part of release_requests on
behalf of the shared promise. Allocation is now deferred to first use, which
relieves release_requests() from all allocation duties. All it needs to do is
free the old object and signal to the its user that an allocation is needed (by
storing {} into the shared_promise).

This patch ensures that when the schema is dense, regardless of
compact_storage being set, the single regular columns is translated
into a compact column.
This fixes an issue where Thrift dynamic column families are
translated to a dense schema with a regular column, instead of a
compact one.
Since a compact column is also a regular column (e.g., for purposes of
querying), no further changes are required.

Fixes#1535.
data_consume_rows_context needs to have close() called and the returned
future waited for before it can be destroyed. data_consume_context::impl
does that in the background upon its destruction.
However, it is possible that the sstable is removed before
data_consume_rows_context::close() completes in which case EBADF may
happen. The solution is to make data_consume_context::impl keep a
reference to the sstable and extend its life time until closing of
data_consume_rows_context (which is performed in the background)
completes.
Side effect of this change is also that data_consume_context no longer
requires its user to make sure that the sstable exists as long as it is
in use since it owns its own reference to it.
Fixes#1537.

Fix runaway task queue growth on cpu-bound loads.
This series adds the ability for partition cache to keep information
whether partition size makes it uncacheable. During, reads these
entries save us IO operations since we already know that the partiiton
is too big to be put in the cache.
First part of the patchset makes all mutation_readers allow the
streamed_mutations they produce to outlive them, which is a guarantee
used later by the code handling reading large partitions.

The current code assumes cell names are always compound and may
wrongly report a non-static row as such, since it looks at the first
bytes of the name assuming they are the component's length.
Tables with compact storage (which cannot contain static rows) may not
have a compound comparator, so we check for the table's compoundness
before checking for the static marker. We do this by delegating to
composite_view::is_static.

composite_view's is_static function is wrong because:
1) It doesn't guard against the composite being a compound;
2) Doesn't deal with widening due to integral promotions and

Promoted index may cause sstable to have range tombstones duplicated
several times. These duplicates appear in the "wrong" place since they
are smaller than the entity preceeding them.
This patch ignores such duplicates by skipping range tombstones that are
smaller than previously read ones.
Moreover, these duplicted range tombstone may appear in the middle of
clustering row, so the sstable reader has also gained the ability to
merge parts of the row in such cases.

This patch changes the column_visitor so that it preservers the order
of the partitions it visits when building the accumulation result.
This is required by verbs such as get_range_slice, on top of which
users can implement paging. In such cases, the last key returned by
the query will be that start of the range for the next query. If
that key is not actually the last in the partitioner's order, then
the new request will likely result in duplicate values being sent.
