IMPALA-7599: make the number of local cache retries configurable
Under heavy read/write load, the number of retries needed for queries
in order to skip over inconsistent metadata exceptions needs to be set
higher. This change makes the number of retries configurable. It can be
set with the newly added flag --local_catalog_max_fetch_retries.
In addition, this change increases the default from 10 to 40, which was
sufficient when handling several workloads with high read/write load.
Made several fixes to exception messages.
Testing:
- manual tests
- added an e2e test that sets the flag and checks for inconsistent metadata
