Description of problem:
After a replica is uninstalled, the host record is still available on the
master. A ipa host-show on this server indicates keytab is still true. Should
have been cleared.
  Host name: ipa-replica.testrelm
  Principal name: host/ipa-replica.testrelm@TESTRELM
  Keytab: True
  Password: False
  Managed by: ipa-replica.testrelm

Also when reinstalling replica, have to first run host-del on master to delete
this host. So - can it be deleted as part of the uninstall, so that there is no
prep for reinstall?

Version-Release number of selected component (if applicable):
ipa-server-2.1.3-4.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. Install master, replica
2. Uninstall replica
3. run ipa host-show <replica host>
