MXS-1929: Make services destroyable

Browse Source 
Services can now be destroyed if they have no active listeners and they
are not linked to servers. When these conditions are met, the service will
be destroyed when the last session for the service is closed.

The closing of a service will close all listeners that were once assigned
to the service. This allows closing of the ports at runtime which
previously was done only on shutdown.

Exposed the command through the REST API but not through MaxAdmin as it is
deprecated.
