fix mounts not loading at deploy for ssh-proxy

Since we used to run the ansible roles for cluster hooks at build time and we don't have headnode of the cluster reachable during the build we just added the mount points to fstab in ansible tasks.

However, we now run these roles during the deploy time and they need to be mounted explicitly mounted so we need to add a task that actually mounts the dirs via ansible that runs during deploy to define cluster hooks
