Burak Yucesoy 5be6eb9ef6 Increase coverage of isolation tests - Part 2 
With this PR we add isolation tests for

COPY to reference table vs. other operations
COPY to partitioned table vs. other operations
Multi row INSERTs vs other operations
INSERT/SELECT vs. other operations
UPSERT vs. other operations
DELETE vs. other operations
TRUNCATE vs. other operations
DROP vs. other operations
DDL vs. other operations

other operations consist of basic SQL operations (like SELECT,
INSERT, DELETE, UPSERT, COPY TRUNCATE, CREATE INDEX) as well
as some Citus functionalities (like master_modify_multiple_shards,
master_apply_delete_command, citus_total_relation_size etc.)

Onder Kalaci c7bb29b69e Prevent maintanince deamon crashes due to dead processes 
If after the distributed deadlock detection decides to cancel
a backend, the backend has been terminated/killed/cancelled
externally, we might be accessing to a NULL pointer. This commit
prevents that case by ignoring the current distributed deadlock.

Jason Petersen 8cb69e3a14 Add alias for target in multi-row INSERTs 
This is necessary for multi-row INSERTs for the same reasons we use it
in e.g. UPSERTs: if the range table list has more than one entry, then
PostgreSQL's deparse logic requires that vars be prefixed by the name
of their corresponding range table entry. This of course doesn't affect
single-row INSERTs, but since multi-row INSERTs have a VALUE RTE, they
were affected.

The piece of ruleutils which builds range table names wasn't modified
to handle shard extension; instead UPSERT/INSERT INTO ... SELECT added
an alias to the RTE. When present, this alias is favored. Doing the
same in the multi-row INSERT case fixes RETURNING for such commands.

Hadi Moshayedi e5fbcf37dd Add Savepoint Support (#1539) 
This change adds support for SAVEPOINT, ROLLBACK TO SAVEPOINT, and RELEASE SAVEPOINT.

When transaction connections are not established yet, savepoints are kept in a stack and sent to the worker when the connection is later established. After establishing connections, savepoint commands are sent as they arrive.

This change fixes #1493 .

Onder Kalaci 205501532a Add version check to the maintenance daemon 
We should prevent running the deadlock detection if

This change fixes a use-after-free bug while renaming obsolete
`pg_worker_list.conf` file, which causes Citus to crash during upgrade
(or even extension creation) if `pg_worker_list.conf` exists.
