IMPALA-8984: Fix race condition in creating Kudu table
This patch fixed the race condition when use 'CREATE IF NOT EXISTS' to
create kudu managed table without Kudu-HMS Integration. This bug would
caused table deleted in Kudu storage, but reserved in HMS when multiple
identical queries submitted at the same time.
Fix is to check whether table already exists in HMS after obtain the
'metastoreDdlLock_' lock. If true, just return 'Table already exists'
tip, otherwise create a new table in HMS and then update catalog.
Tests:
* Add fe test MultiKuduDDLTest.java
* Ran all front-end tests
