Description

TxnHandler has some bad logging, like:

LOG.debug("Going to execute query<" + txnsQuery + ">");

https://github.com/apache/hive/blob/8e39937bdb577bc135579d7d34b46ba2d788ca53/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/txn/TxnHandler.java#L533

this will involve a pretty unnecessary string concatenation in production when we're on INFO level usually, let's use string formats
