ipatests: wait while http/ldap/pkinit cert get renew on replica
    
    LDAP/HTTP/PKINIT certificates should be renewd on replica after
    moving system date. Test was failing because ipa-cert-fix ran
    while these cert was not renewd and it tried to fix it.
    
    This test adds check for replication before calling ipa-cert-fix
    on replica.
