Our external repos are already signed repo, so let's enable secure-apt.
Seems like more recent version of Ubuntu (tested on 18.04) does not accept
skipping GPG check, so we need it anyway in near future.

Now we can cross build our .rpm/.deb packages, so let's extend AMI build script
to support cross build, too.
Also Ubuntu 16.04 support added, since it's latest Ubuntu LTS release.

Also handle exceptions thrown by has_existing_roles(), and print a

This follows the implementation in Apache Cassandra. The auth tasks
executed by delay_until_system_ready() usually perform a query with
QUORUM consistency level, which can fail if some nodes are
unavailable. So, we provide both exception handling and a retry
mechanism.

has_existing_roles() creates a seastar thread, but that can be
lifted to the caller for prettier code.

We are getting package build error on dh_auto_install which is invoked by
pybuild.
But since we handle all installation on debian/scylla-server.install, we can
simply skip running dh_auto_install.

"This series makes it easier to comprehend assertion failures which
involve printing mutation contents."
* 'tgrabiec/mutation-printout' of github.com:scylladb/seastar-dev:
tests: Introduce mutation_diff script
mutation: Make printout more concise
mutation_partition: Don't print absent elements
mutation_partition: Make row_marker printout similar to other partition elements
database: Move operator<<() overloads to appropriate source files
mutation_partition: Use multi-line printout
position_in_partition: Improve printout
Convert to a multi line output, which is easier to read for a human.

Benefits:
- most significant parts appear first.
bound_weight, which is least significant, was in the middle before.
- shorter, so a bit easier to parse assertion failures.
The universal reference was introduced so we could bind an rvalue to
the argument, but it would have sufficed to make the argument a const
reference. This is also more consistent with the function's other
overload.

576ea421dc introduced a regression
as it didn't change the assumption that all clustering elements where
compound when writing a range tombstone, compound or non-compound, as
compound. Thus, we serialized a non-compound element while we should
have serialized a compound one.

after 7f8b62bc0b, its move operator and ctor broke. That potentially
leads to error because data_consume_context dtor moves sstable ref
to continuation when waiting for in-flight reads from input stream.
Otherwise, sstable can be destroyed meanwhile and file descriptor
would be invalid, leading to EBADF.
Fixes#3020.

"This simplifies implementation of mutation_partition merging by relaxing
exception guarantees it needs to provide. This allows reverters to be dropped.
Direct motivation for this is to make it easier to implement new semantics
for merging of clustering range continuity.
Implementation details:
We only need strong exception guarantees when applying to the memtable, which is
using MVCC. Instead of calling apply() with strong exception guarantees on the latest
version, we will move the incoming mutation to a new partition_version and then
use monotonic apply() to merge them. If that merging fails, we attach the version with
the remainder, which cannot fail. This way apply() always succeeds if the allocation
of partition_version object succeeds.

The uses which needed strong or weak exception guarantees were

uses don't need any exception guarantees.
