DESCRIPTION: Adds PG16Beta3 support
This is the final commit that adds
PG16 compatibility with Citus's current features.
You can use Citus community with PG16Beta3. This commit:
- Enables PG16 in the configure script.
- Adds PG16 tests to CI using test images that have 16beta3
- Skips wal2json cdc test since wal2json package is not available for PG16 yet
- Fixes an isolation test
Several PG16 Compatibility commits have been merged before this final one.

As of master branch, Citus does all the modifications to replicated tables
(e.g., reference tables and distributed tables with replication factor > 1),
via 2PC and avoids any shardstate=3. As a side-effect of those changes,
handling node failures for replicated tables change.
With this PR, when one (or multiple) node failures happen, the users would
see query errors on modifications. If the problem is intermitant, that's OK,
once the node failure(s) recover by themselves, the modification queries would
succeed. If the node failure(s) are permenant, the users should call
`SELECT citus_disable_node(...)` to disable the node. As soon as the node is
disabled, modification would start to succeed. However, now the old node gets
behind. It means that, when the node is up again, the placements should be
re-created on the node. First, use `SELECT citus_activate_node()`. Then, use
`SELECT replicate_table_shards(...)` to replicate the missing placements on
the re-activated node.
In our testing infra structure, even though we use pinned versions of postgres, the auxiliary libraries might pull in newer versions. This is for example the case for libpq, which will now use the libpq libraries from 14beta3.
The changes in this PR are a lot due to the libpq changes.
We also have changed the citus version that is used as a base for the citus upgrades, from 10.0 to 10.1 . This caused columnar to enforce some extra limits on the settings, which conflicted with our upgrade tests.
The changes in failure tests are due to the libpq changes.
There are also a lot of changes on isolation tests outputs, hence we
updated all of them.
