### What changes were proposed in this pull request? When loading DataFrames from JDBC datasource with Kerberos authentication, remote executors (yarn-client/cluster etc. modes) fail to establish a connection due to lack of Kerberos ticket or ability to generate it. This is a real issue when trying to ingest data from kerberized data sources (SQL Server, Oracle) in enterprise environment where exposing simple authentication access is not an option due to IT policy issues. In this PR I've added MS SQL support. What this PR contains: * Added `MSSQLConnectionProvider` * Added `MSSQLConnectionProviderSuite` * Changed MS SQL JDBC driver to use the latest (test scope only) * Changed `MsSqlServerIntegrationSuite` docker image to use the latest * Added a version comment to `MariaDBConnectionProvider` to increase trackability ### Why are the changes needed? Missing JDBC kerberos support. ### Does this PR introduce _any_ user-facing change? Yes, now user is able to connect to MS SQL using kerberos. ### How was this patch tested? * Additional + existing unit tests * Existing integration tests * Test on cluster manually Closes #28635 from gaborgsomogyi/SPARK-31337.
