Update murano service name

In Mitaka, the service name must have a dash rather than underscore when using
the sql catalog driver in Keystone[0] (the default).

This works for upgrade also, though further improvements could be written to
remove the old endpoint from Keystone, and automatically chose a dash or
underscore based on driver type used.
