added pause attribute to the aci_config_rollback about ansible-aci

[sstotko]

I just tested this with the "pause" attribute from the ansible:devel branch but I still get the same error (the pause isn't included in the latest collection 2.4.0).
The result is the same with cisco.aci.aci_config_rollback from thew 2.4.0 collection and the ansible:devel branch.

5.2.4e

Running the request directly on the APIC works:

apick003# icurl -sg 'http://localhost:7777/mqapi2/snapshots.diff.xml?s1dn=uni/backupst/snapshots-[uni/fabric/configexp-ansible_snapshot]/snapshot-run-2023-02-14T07-53-22&s2dn=uni/backupst/snapshots-[uni/fabric/configexp-ansible_snapshot]/snapshot-run-2023-02-14T07-54-29'
<?xml version="1.0" encoding="UTF-8"?><polUni rn="uni" status="" userdom="all">
...

This takes 4-5 seconds to complete but yields a result.

It would be great if this worked with the module.

@sstotko I just ran the module against a configuration we use for the test and it passed.
Can you please share the playbook with minimal configuration which is failing for you?

@shrsr I'm calling a role with the following task (copied from the examples):
