Add --exclude-table flag to ignore changes in certain tables

[andreyrusanov]

Description

This PR adds the --exclude-table flag, which ignores changes in all tables whose names match the provided regular expression.

Motivation

I initially encountered a lack of support for partitioned tables, as well as issues with temporary tables in several non-production environments.
While partitioned tables require a more nuanced solution, the ability to ignore specific tables is a low-hanging fruit that addresses several pain points.

Testing

I tested commands like apply with --exclude-table flag, e.g.

./pg-schema-diff apply --to-dir /path/to/schema --from-dsn "postgresql://postgres@mydb:5432/db" --disable-plan-validation  --allow-hazards ACQUIRES_ACCESS_EXCLUSIVE_LOCK,DELETES_DATA,INDEX_BUILD,INDEX_DROPPED,ACQUIRES_ACCESS_EXCLUSIVE_LOCK,DELETES_DATA,HAS_UNTRACKABLE_DEPENDENCIES,IMPACTS_DATABASE_PERFORMANCE --exclude-table partitioned_table_\*
