Add `mssql` test integration

[Taragolis]

Body

After removal Microsoft SQL Server as DB Backend (https://lists.apache.org/thread/pgcgmhf6560k8jbsmz8nlyoxosvltph2) we lost an ability to run unit tests over MS SQL database. All unit tests which rely on mssql moved into the integration tests (see #38530):

• tests/providers/apache/hive/transfers/test_mssql_to_hive.py -> tests/integration/providers/apache/hive/transfers/test_mssql_to_hive.py
• tests/providers/google/cloud/transfers/test_bigquery_to_mssql.py -> tests/integration/providers/google/cloud/transfers/test_bigquery_to_mssql.py
• tests/providers/google/cloud/transfers/test_mssql_to_gcs.py -> tests/integration/providers/google/cloud/transfers/test_mssql_to_gcs.py

We should eventually add MS SQL as available option for integration tests, and make to possible to run integration tests with it
