We had a discussion about this topic on a meeting and we have agreed on
removing the selfsign completely. This will still not be end of  the world for
users running selfsign servers (if there are any) as they could use the new
CA-less feature to generate certs for replica or other certs.

Moving to review of this patch.

1) Upgrade of the actual selfsigned server did not seem to work for me:

selfsigned master broke after I upgraded from 3.1.3 selfsigned server.

Maybe the reason is that the selfsign server's default.conf has still enable_ra
set to "True"?

# cat /etc/ipa/default.conf
[global]
host=vm-037.idm.lab.bos.redhat.com
basedn=dc=idm,dc=lab,dc=bos,dc=redhat,dc=com
realm=IDM.LAB.BOS.REDHAT.COM
domain=idm.lab.bos.redhat.com
xmlrpc_uri=https://vm-037.idm.lab.bos.redhat.com/ipa/xml
ldap_uri=ldapi://%2fvar%2frun%2fslapd-IDM-LAB-BOS-REDHAT-COM.socket
enable_ra=True
mode=production


2) Upgrade of a selfsigned replica seemed OK, but I still see its httpd and
dirsrv certificates being tracked by certmonger, when I list them with
"ipa-getcert list"...
