This change is built on top of #1741 #1740. This extracts out the logic of starting a thrift hive metastore server into a separate class, which will allow for more modular support of additional listeners in the future, while also cleaning up the current hivemetastore.java file. ### Why are the changes needed? This will allow for more modular support of additional listeners in the future (such as grpc) since now there is a common interface to implement that isn't based around thrift solely. ### Does this PR introduce _any_ user-facing change? no ### How was this patch tested? Existing unit tests should cover the changes made here, since this is a refactoring. This is an automated message from the Apache Git Service.
