CLI commands should be equivalent of starting a new session, running equivalent stored procedure, and closing session

[timsehn]

This came up in the context of replication where a command line dolt commit did not trigger replication but dolt sql -q "call dolt_commit()" did. Makes no sense.

We need to where a stored procedure exists make the CLI behave as if:

1. We connected to the server via a new session
2. We ran the equivalent stored stored procedure
3. We closed the session

This is a much easier model to explain to customers.

For CLI commands that don't have equivalent stored procedures we're free to deviate from the above.
