Reduces processing overhead and network traffic.
We can't use the NO_METADATA flag in the metadata object, because this
is a request attribute; different executions of the same prepared statement
can have different settings for skip_metadata.

"This patch series adds CQL front-end support for secondary indices. You
can now execute CREATE INDEX and DROP INDEX statements, which will
update the newly added "Indexes" system table. However, the indexes are
not actually backed up by anything nor are they available for CQL
queries. The feature is hidden behind a new cluster feature flag and
enabled only with the "--experimental" flag."

Fix the CQL front-end to populate the partition key bind index array in
result message prepared metadata, which is needed for CQL binary
protocol v4 to function correctly.
Fixes#2355.

"This series introduces partial support for range deletions. This allows
deletion operations such as
delete from cf where p=1 and c > 0 and c <= 3.
This series only adds support for single-column range restrictions.
We enforce that both range bounds be specified, because we can't represent
infinite bounds in the current sstable format. Such bounds are represented
as a prefix with no components, with the bound_kind informing whether they
are a bottom of top bound.
We're currently unable to serialize an infinite bound in such a way that it
would be correctly interpreted by Cassandra 2.2.x. A serialized bound is a
composite with a (<length><value><EOC>)+ format. While we could technically
represent the bottom bound, the top bound, if written as a single component
with 0 bytes in size and some EOC, would always sort before other values.
The same would happen if represented as an empty (no components) composite,
because in Cassandra 2.2.x those always have EOC = NONE.
This limitation should stay in place until we can properly represent range
tombstones in the storage format."

Current script has a bug that overwrites symlink on

SELinux because of it.
So keep symlink after modifying the file.

This is a folded version of the following rework on the node health
check script:
- Added support for non-default cql + nodetool ports
- Script will not exit if either Scylla-server / Scylla-jmx / Both
services are not up and running. It will alert the user about it and
which output cannot be collected, but continue collecting everything
else.
- Removed lshw installation and non-needed use in commands
- Script supports RHEL/CentOS/Ubuntu14/Ubuntu16/Debian (tested on all
beside Debian, should behave the same as Ubuntu14/16)
- All Indentation issues fixed -> using only tab (no spaces)
consistently.
- >> vs. > was fixed as well in the needed places.
- Changes the ${VAR_NAME} instances to $VAR_NAME, and kept the {} only
where needed.
- Check Scylla service as Vlad recommended using 'ps -C'
- Fixed the CQL not listening error message.
- Added Sanity check if script is attempted to run on non-Fedora and
non-Debian OS -> alert the user and exit.
- Removed the MANUAL CHECK LIST section (moved to Google Forms)
- Added date in head of the report.
- Removed text from Report's "PURPOSE" section, which was referring to
the "MANUAL CHECK LIST" (not needed anymore).

"gcc 7 doesn't like some of our code, so adjust to make it happy."

Remove exception specifications
commitlog: handle noexcept conflict between unlink and function object
thrift: change generated code namespace
org::apache::cassandra (the generated namespace name) gets confused with
apache::cassandra (the thrift runtime library namespace), either due to
changes in gcc 7 or in thrift 0.10. Either way, the problem is fixed
by changing the generated namespace to plain cassandra.

Change the clustering key argument in mutation::set_cell from
exploded_clustering_prefix to clustering_key_prefix, which allows for
some overall code simplification and fewer copies. This mostly affects
the cql3 layer.

This patch ensures the different mutation_partition::apply_delete()
overloads behave similarly, so that, for example, an empty clustering
key is treated the same way as an empty
exploded_clustering_key_prefix.

This patch replaces the custom where clause processing by adding and
using a statement_restrictions field to modification_statement.
This improves code reuse and also moves some checks to prepare-time.
