CASMTRIAGE-7301: Ansible play to create iscsi-sbps-targets should not delegate to localhost
  - fixed the tasks, update file (with host, HSN and NMN info) and creation of DNS SRV and A records
    to delegate to one of the worker nodes instead of localhost.

Summary and Scope

One of the tasks of role csm.sbps.dns_srv_records was failing when running in CFS environment when compared to running with standard ansible-playbook command. This was due to the reason of "delegate_to: localhost" where the tasks were delegated to run inside the CFS k8s job (in non CFS case "delegate_to: localhost" would be the master node where plays are getting executed) and failing with kubectl command not found error. Two specific tasks under this role are supposed to be run either on master node or on one of the worker nodes instead of running locally inside the CFS k8s job.

Fixed these two specific tasks to run on the 1st worker from the host inventory group (Management_Worker) and that is the best fix is what I see as we can't run these tasks on master node (original intention) in CFS environment with current _delegate_to: "{{ play_hosts | first }}"_fix when inventory is "Management_Worker". Here it will now update the file "/tmp/hsn_nmn_info.txt" on the first worker as well as invoke creation of the DNS SRV and S records on the same worker referring to "/tmp/hsn_nmn_info.txt" that should solve the purpose.

Test description:

Verified the fix by running the ansible plays with CFS session/ config. Observed that all the tasks have been completed
successfully in CFS environment without any fail and also the DNS SRV and A records are created (tasks where the fix is actually applied).
