[ClusterLabs] notify action is not called for the docker bundle resources

[Numan Siddique]

Hi,

I am creating a redis bundle resource (master - slave mode). It is creating
successfully, but I am noticing that "notify" action is not called by
pacemaker_remoted.

Below are the steps I used to create the redis bundle resource [1].  The
sosreport can be found here - [2]

I am seeing the same behaviour when I create the "ovndb-servers" [3] bundle
resource (master/slave) as well.
In the case of ovndb-servers OCF resource, we rely on notify action to
change the mode of the OVN Db server to active or backup.

Can some one please help me on why notify action is not called ? Is there
something wrong in my setup ? Or bundle resources lack the support to call
notify actions ?
