IMPALA-14306: Frontend.getDataSrcs() should retry for
InconsistentMetadataFetchException
After IMPALA-14283, coordinator will throw an
InconsistentMetadataFetchException when witness catalogd service ID
changes. The Frontend code should retry the request to use fresh
metadata. This patch resolves the TODO item in Frontend.getDataSrcs() to
add the retry as other methods do. Also change the catch clause in
LocalCatalog.getDataSources() so InconsistentMetadataFetchException can
be thrown from it.
Tests:
- Ran TestExtDataSources.test_catalogd_ha_failover 100 times.
