[WIP] JDBC: Static SQL

[singhpk234]

About the change

Static SQL is preferred over runtime SQL generation

• This change gets rid of almost all runtime SQL generation barring the IN query where the size is not available until runtime.
• Move the realm_id to the model to simplify the parameter feeding to the PreparedQuery
• Completely gets rid of QueryGenerator class and it's tests

Pending

• Refactor the databaseType conversions to abstract it away from the mode
• Refactor the DataSourceOperations to incorporate the databaseType presently it kind of is spread to MetastoreManagerFactory
• Find better ways to bind the query currently we are using the ordered DS to feed it to the query.

Testing

Existing test pass
