do not use master role with function hosts_as()

Better to define following roles into nodeset :

  • ipaservera and master for the SUT ipa master.
  • ipaserverb and agent for the SUT ipa replica.
  • ipaclientcentos and agent for SUT ipa client running centos7
  • ipaclientubuntu and agent for SUT ipa client running ubuntu1604

Then use roles ipaservera, ipaserverb, ipaclientcentos and ipaclientubuntuwith functionhosts_as()`.
