How to support RDBMS UPDATE, DELETE, and INSERT SQL statements with JdbcStoragePlugin

@cgivre Does your company have such a demand?

[cgivre]

Yes actually. We've discussed working on this and looked into it a bit. Our priority would be INSERT statements. The good news is that Calcite already supports it, so the framework is already there. We'd just have to write a handler so that Drill knows what to do with the query plan.

I actually started a branch with some experimentation for this. Take a look if you'd like: https://github.com/cgivre/drill/tree/add_insert
