    build: Decouple the identity service from the Kerberos provider
    
    A subsequent commit will add a provider for the Fedora Account System,
    which will be a branded Kerberos provider. To support enabling and
    disabling the Fedora and Kerberos providers independent of each other,
    it is necessary to introduce a separate variable to govern the building
    of the identity service, which will be shared by the two.
