This commit backports changes related to HIVE-19416, HIVE-20293, HIVE-20117, HIVE-18453, HIVE-20833, HIVE-21498
Commits - Reasons

1. Fixed test materialized_view_create_rewrite - This commit removes the extra lines that came up while cherry picking HIVE-19416
2. HIVE-20833 Remaining fix for PARAM_VALUE as CLOB - When HIVE-20833 was cherry picked to branch-3, there was one remaining occurence of PARAMS_VALUE as VARCHAR so cherry picked that partial change from master.
3. Ignored testReplCM test - This test was not present in master.
4. Partial HIVE-20966 for Hive.java - HIVE-20966 ensured that when createPartitions was called, we passed WRITE_IDs down the function call. Because this ticket was meant for other purposes, we will cherry pick the entire ticket as separate one (if needed). There were test failures related to partitions and that was because partitions did not have valid write ids and hence transactions were not getting committed successfully.
5. Test fixes TestLlapLocalCliDriver - The justification of fixing respective tests :
   acid_stats*.q.out - These are minor refactorings (Not major changes)
   acid_table_stats.q.out - These were the changes committed as per HIVE-19416. These were not cherry picked since the test
   q.out file will be different for branch-3 and cannot be cherry-picked directly.
   acid_no_buckets.q.out - This change was again part of HIVE-19416 just added this test in a different commit.
   materialized_view_create_rewrite_.q.out - Test differences are due to enabling transaction stats (HIVE-19416) and this ticket
   had changes in materialized_view_create_rewrite_3.q.out, so extrapolated the same to these test files.
   results_cache_truncate.q.out - Again inline with HIVE-19416, but committed separately.
   union7.q.out - Minor refactorings. The values are reordered nothing changes.
   stats.q.out - Completely inline with HIVE-19416. Committed separately because of merge conflicts with q.out files.
   materialized_*.q.out changes- HIVE-20115
6. Test fixes - These fixes were expected after HIVE-19416 was committed to master.
