Bump Ansible SSH ControlPersist param to 300s

We see the following error downstream [1], [2] indicates this error is
caused by the SSH socket Ansible creates to multiplex connections fails.

Rather than handling the failure, Ansible fails the task. This is
reportedly failing around 30% of the time on a very long running CI job.

300s was selected as it's used by the openstack-ansible project [3] [4]
