[WIP] Non Serializable extra info in session is overwritten from stale
thread
Problem:
1. Non Serializable extra info is copied from thread which causes
stale data from old session when the thread is reused by spark.
2. CarboSessionInfo clone is not copying Non serializable info to
new object which can damage session level values if local query thread updates
values.
Solution: Remove logic to copy Non Serializable extra info and fix clone
logic
