This MR goal is to use the queries "GRANT privileges TO ALL TABLES IN SCHEMA/DB" instead of creating a query by table when in the spec file there is permissions applied to all tables in db / schema : db.*.* or db.schema.* in order to decrease a lot the computing cost by decreasing the number of queries generated.

Changes:

Unrelated to the issue:

• commit Use stable black version: I had to change the black version for a stable one because I had issues with click in pre-commit, as in this stackoverflow question

Related to the issue:

In src/permifrost/snowflake_grants.py:

• I added the GRANT_ALL_PRIVILEGES_TEMPLATE and used it as FUTURE GRANTS are used for write and read on tables: Add grant on all tables in object queries for write and read privileges

• grouped the if clauses for the database level (there was 2 if doing the same thing): Regroup redundant if clauses

• fixed wrong permissions given for views in the database level (all write permissions instead of just select): Fix wrong permissions for write view grants at database level

• Upd related tests, so removed the table level assertion and add the GRANT ALL assertion. As with this changes the table level was not tested anymore I added a new test with a permission at a table level. Update tests for grant privileges on all queries

• closes #112 (closed)

No documentation changes as this functionality is said done in the README.md here
