[HUDI-8534] Ensure index creation is idempotent in face of failures

[lokeshj1703]

Change Logs

We need to ensure the user can execute CREATE INDEX name .... with same name, failing many times and then be able to eventually succeed with the right syntax/parameters.

spark-sql (default)> create index idx_bloom on hudi_table using bloom_filter(city) options(func='lower');

java.lang.IllegalArgumentException: The value of hoodie.functional.index.type should be one of COLUMN_STATS,BLOOM_FILTERS,SECONDARY_INDEX, but was bloom_filter

spark-sql (default)> create index idx_bloom on hudi_table using bloom_filters(city) options(func='lower');

The PR ensures that the metadata related to index is deleted in case creation fails. For this we make a call to drop the corresponding index if its creation fails. The drop call ensures that any metadata for the index is deleted.
