For 4.5, with move to pegasus service and reliance on a database schema for it, we will have a new tool called pegasus-db-admin, that can be used to upgrade the schema's for existing pegasus install.

For 4.5, an ability to rename the dashboard database tables will be required, since the table names clash with monitord databases. The tool should also have a --check option that will return whether a database is upgraded or not.

The new tool should have the logic from
- pegasus-service-admin migrate option
- and the upgrade script for JDBCRC for 4.4
