Description of problem:[ceph-ansible] 5.0 - ceph-ansible adoption playbook doesn't support collocated daemons 


Version-Release number of selected component (if applicable):
[ceph: root@ceph-monitor-1 /]# ceph version
ceph version 16.2.0-143.el8cp (0e2c6f9639c37a03e55885fb922dc0cb1b5173cb) pacific (stable)

How reproducible:


Steps to Reproduce:
 1. Install 4.2 build on fresh cluster
2. Configure iscsi configuration on the cluster with 34 clients
3. Upgrade to 5.0 from 4.2 baremetal 
4. Convert the storage cluster daemons to run cephadm.
5. Check the status
Actual results: ceph-adopt playbook fails with the following error

'Error: error creating container storage: the container name "cephadm" is already in use by "fed70fef19da0fbae1f01afc2412217211eab009941bdac6f7b6c26d2c96c13b". You have to remove that container to be able to reuse that name.: that name is already in use'


complete output of playbook is pasted in the below

Expected results:
We should not see any error when daemons are collocated and ceph-adopt playbook is performed
