Remove task tracker executor (#3850) 

* use adaptive executor even if task-tracker is set

* Update check-multi-mx tests for adaptive executor

Basically repartition joins are enabled where necessary. For parallel
tests max adaptive executor pool size is decresed to 2, otherwise we
would get too many clients error.

* Update limit_intermediate_size test

It seems that when we use adaptive executor instead of task tracker, we
exceed the intermediate result size less in the test. Therefore updated
the tests accordingly.

* Update multi_router_planner

It seems that there is one problem with multi_router_planner when we use
adaptive executor, we should fix the following error:
+ERROR:  relation "authors_range_840010" does not exist
+CONTEXT:  while executing command on localhost:57637

* update repartition join tests for check-multi

* update isolation tests for repartitioning

* Error out if shard_replication_factor > 1 with repartitioning

As we are removing the task tracker, we cannot switch to it if
shard_replication_factor > 1. In that case, we simply error out.

* Remove MULTI_EXECUTOR_TASK_TRACKER

* Remove multi_task_tracker_executor

Some utility methods are moved to task_execution_utils.c.

* Remove task tracker protocol methods

* Remove task_tracker.c methods

* remove unused methods from multi_server_executor

* fix style

* remove task tracker specific tests from worker_schedule

* comment out task tracker udf calls in tests

We were using task tracker udfs to test permissions in
multi_multiuser.sql. We should find some other way to test them, then we
should remove the commented out task tracker calls.

* remove task tracker test from follower schedule

* remove task tracker tests from multi mx schedule

* Remove task-tracker specific functions from worker functions

* remove multi task tracker extra schedule

* Remove unused methods from multi physical planner

* remove task_executor_type related things in tests

* remove LoadTuplesIntoTupleStore

* Do initial cleanup for repartition leftovers

During startup, task tracker would call TrackerCleanupJobDirectories and
TrackerCleanupJobSchemas to clean up leftover directories and job
schemas. With adaptive executor, while doing repartitions it is possible
to leak these things as well. We don't retry cleanups, so it is possible
to have leftover in case of errors.

TrackerCleanupJobDirectories is renamed as
RepartitionCleanupJobDirectories since it is repartition specific now,
however TrackerCleanupJobSchemas cannot be used currently because it is
task tracker specific. The thing is that this function is a no-op
currently.

We should add cleaning up intermediate schemas to DoInitialCleanup
method when that problem is solved(We might want to solve it in this PR
as well)

* Revert "remove task tracker tests from multi mx schedule"

This reverts commit 03ecc0a681.

* update multi mx repartition parallel tests

* not error with task_tracker_conninfo_cache_invalidate

* not run 4 repartition queries in parallel

It seems that when we run 4 repartition queries in parallel we get too
many clients error on CI even though we don't get it locally. Our guess
is that, it is because we open/close many connections without doing some
work and postgres has some delay to close the connections. Hence even
though connections are removed from the pg_stat_activity, they might
still not be closed. If the above assumption is correct, it is unlikely
for it to happen in practice because:
- There is some network latency in clusters, so this leaves some times
for connections to be able to close
- Repartition joins return some data and that also leaves some time for
connections to be fully closed.

As we don't get this error in our local, we currently assume that it is
not a bug. Ideally this wouldn't happen when we get rid of the
task-tracker repartition methods because they don't do any pruning and
might be opening more connections than necessary.

If this still gives us "too many clients" error, we can try to increase
the max_connections in our test suite(which is 100 by default).

Also there are different places where this error is given in postgres,
but adding some backtrace it seems that we get this from
ProcessStartupPacket. The backtraces can be found in this link:
https://circleci.com/gh/citusdata/citus/138702

* Set distributePlan->relationIdList when it is needed

It seems that we were setting the distributedPlan->relationIdList after
JobExecutorType is called, which would choose task-tracker if
replication factor > 1 and there is a repartition query. However, it
uses relationIdList to decide if the query has a repartition query, and
since it was not set yet, it would always think it is not a repartition
query and would choose adaptive executor when it should choose
task-tracker.

* use adaptive executor even with shard_replication_factor > 1

It seems that we were already using adaptive executor when
replication_factor > 1. So this commit removes the check.

* remove multi_resowner.c and deprecate some settings

* remove TaskExecution related leftovers

* change deprecated API error message

* not recursively plan single relatition repartition subquery

* recursively plan single relation repartition subquery

* test depreceated task tracker functions

* fix overlapping shard intervals in range-distributed test

* fix error message for citus_metadata_container

* drop task-tracker deprecated functions

* put the implemantation back to worker_cleanup_job_schema_cachesince citus cloud uses it

* drop some functions, add downgrade script

Some deprecated functions are dropped.
Downgrade script is added.
Some gucs are deprecated.
A new guc for repartition joins bucket size is added.

* order by a test to fix flappiness
