Improve error messages in ipa-replica-manage.

Correctly handle case where we bind using GSSAPI with an unauthorized user.

Remove extraneous except clause. We now have handle for LDAP errors.

Make it explicit in a few places what server we can't connect to.

When the remote replica is down and we are forcing its removal, remove
a duplicate entry from the list of servers to remove.
