Handle multiple column secondary indexes

Currently users can create only one  column in a secondary index. The Jira aims to support multiple columns secondary indexes.
{code:java}
CREATE INDEX [IF NOT EXISTS] index_name
ON table_name(column1, column2, ...); {code}
Also we need to handle Metadata table validator so that it can validate multiple secondary indexes instead of one. Also add tests in TestHoodieMetadataTableValidator to verify the multiple indexes.
