Seperate install of services and start scripts:

This allows openstack services to be git/pip installed
without installing any startup scripts.

This is useful for keystone-db or nova-db elements, for
example, where the service must be installed to perform
database migration, but no service start scripts need
be installed.

Additionally, add a tool to create openstack sql databases.
