Review request for lens.
Bugs: LENS-743
https://issues.apache.org/jira/browse/LENS-743
Repository: lens
Description
-------
There have to be retries for query failures for transient errors like network
errors (Hive server not reachable/ Metastore not reachable/ DB not reachable).
Retries should be available for each phase - submission, execution, updating
status, fetching results and formatting.
Right now, any such failure results in marking query as failed.
Diffs (updated)
