Changes test files in multi and multi-1 schedules such that they
accomodate coordinator in metadata.
Changes fall into the following buckets:
1. When coordinator is in metadata, reference table shards are present
in coordinator too.
This changes test outputs checking the table size, shard numbers etc.
for reference tables.
2. When coordinator is in metadata, postgres tables are converted to
citus local tables whenever a foreign key relationship to them is
created. This changes some test cases which tests it should not be
possible to create foreign keys to postgres tables.
3. Remove lines that add/remove coordinator for testing purposes.
When trying to fix#6245 I realized that multi_utilities was leaking
some tables that it created during the test. This fixes that by
creating all these tables in a schema that's dedicated for this test.
This commit is inspired by a commit
dc9c3b0ff21465fa89d71eecf5e6cc956d647eca from PostgreSQL 15 that shares
the same header.
I also removed some gitignore rules so that I can add some files to git
worktree. We used to ignore the generated files, that are no longer
generated after this commit.

Below is the commit message from PostgreSQL 15 commit
dc9c3b0ff21465fa89d71eecf5e6cc956d647eca :
"git mv" all the input/*.source and output/*.source files into
the corresponding sql/ and expected/ directories. Then remove
the pg_regress and Makefile infrastructure associated with
dynamic translation.
