gatorsmile b9eafcb526 [SPARK-31088][SQL] Add back HiveContext and createExternalTable ... ### What changes were proposed in this pull request? Based on the discussion in the mailing list [[Proposal] Modification to Spark's Semantic Versioning Policy](http://apache-spark-developers-list.1001551.n3.nabble.com/Proposal-Modification-to-Spark-s-Semantic-Versioning-Policy-td28938.html) , this PR is to add back the following APIs whose maintenance cost are relatively small. - HiveContext - createExternalTable APIs ### Why are the changes needed? Avoid breaking the APIs that are commonly used. ### Does this PR introduce any user-facing change? Adding back the APIs that were removed in 3.0 branch does not introduce the user-facing changes, because Spark 3.0 has not been released. ### How was this patch tested? add a new test suite for createExternalTable APIs. Closes #27815 from gatorsmile/addAPIsBack.
