Try to work around Ansible rc-13 race condition

There is a race condition in Ansible that can result in this failure:
  msg: |-
  MODULE FAILURE
  See stdout/stderr for the exact error
rc: -13
See ansible/ansible#78344 and
ansible/ansible#81777.

In stackhpc/stackhpc-kayobe-config#1108 we applied
a workaround to increase the ControlPersist timeout to 1 hour, but this
does not always work.

Try another workaround of removing the ControlPersist sockets in between
Kayobe runs.
