Damian Dabrowski 9850f00be4 Fix mount's systemd unit dependency logic 
Improve logic for making systemd mount dependent on
network-online.target when network filesystem is being used.

This change improves feature implemented in commit [1].

Currently when device is specified by UUID or LABEL, dependency for
network-online.target is added even it's not a network filesystem.
We should be careful with this as it may create circular dependency.
In my case, circular dependency looked like this:

network.target ->
  network-pre.target ->
    netfilter-persistent.service ->
      local-fs.target ->
        var-lib-nova.mount ->
          network-online.target ->
            network.target

Additionally, this commit was originally supposed to add dependency also
for CIFS mounts(these ones starting from '//') but it never worked in my
opinion. It was also fixed by this change.

Ansible systemd_mount

This Ansible role configures systemd mount files.

This role requires the openstack-ansible-plugins repository to be available on your local system. The Ansible galaxy resolver will not retrieve this role for you. To get the plugins role in place clone the plugins repository before running this role.

# git clone https://github.com/openstack/openstack-ansible-plugins /etc/ansible/roles/plugins

You can also use the ansible-galaxy command on the ansible-role-requirements.yml file.

# ansible-galaxy install -r ansible-role-requirements.yml

Release notes for the project can be found at: https://docs.openstack.org/releasenotes/ansible-role-systemd_mount
