Make service naming in ipa-server-install consistent

Forces more consistency into ipa-server-install output. All
descriptions of services that are not instances of
SimpleServiceInstance are now in the following format:

<Description> (<Service Name>)

Furthermore, start_creation method has been modified to support
custom start and end messages. See documentation for more info.
