Do not record relation accessess unnecessarily 

Before this commit, we've recorded the relation accesses in 3 different
places
    - FindPlacementListConnection         -- applies all executor in tx block
    - StartPlacementExecutionOnSession()  -- adaptive executor only
    - StartPlacementListConnection()      -- router/real-time only

This is different than Citus 8.2, and could lead to query execution times
increase considerably on multi-shard commands in transaction block
that are on partitioned tables.

Benchmarks:

```
1+8 c5.4xlarge cluster

Empty distributed partitioned table with 365 partitions: https://gist.github.com/onderkalaci/1edace4ed6bd6f061c8a15594865bb51#file-partitions_365-sql

./pgbench -f /tmp/multi_shard.sql -c10 -j10 -P 1 -T 120 postgres://citus:w3r6KLJpv3mxe9E-NIUeJw@c.fy5fkjcv45vcepaogqcaskmmkee.db.citusdata.com:5432/citus?sslmode=require

cat  /tmp/multi_shard.sql
BEGIN;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
COMMIT;
cat  /tmp/single_shard.sql
BEGIN;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
COMMIT;

cat  /tmp/mix.sql
BEGIN;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;
	DELETE FROM collections_list WHERE key = :aid;

	DELETE FROM collections_list;
	DELETE FROM collections_list;
	DELETE FROM collections_list;
COMMIT;
```

The table shows `latency average` of pgbench runs explained above, so we have a pretty solid improvement even over 8.2.2.
