Setting the `remount_state` variable to `rw` by default will allow the
`remount.yml` playbook to be "chained" with other playbooks, e.g.:
```
ansible-playbook -l kubelet remount.yml collectd.yml -b
```
Cached facts interfere with the detection of which filesystems need to
be remounted. We need to clear them all and gather again before
beginning to ensure that the correct mounts are considered.
Many hosts have a read-only root filesystem, as well as some other
read-only paths that need to be remounted before configuration changes
can be made. The `remount.yml` playbook can be used to remount select
filesystems as either read-write or read-only (the default). It is
intended to be used before and after other playbooks, to ensure the
filesystems are in the correct state.
