Problem seen:
```
Error: Evaluation Error: Error while evaluating a Resource Statement, Evaluation Error: Unknown variable: '::osfamily'. (file: /etc/puppet/cosmos-modules/augeas/manifests/params.pp, line: 7, column: 8) on node example-1.sunet.se
```
This way we run modules installed from upstream apt packages instead.
Solution to delete keys to use local pacakges from pahol.
While here fix pylint issue with not importing platform module at
beginning of file.
This extends run-cosmos with a new argument that calls the unlock
function already included in the script as well as using the already
existing lock() function to make sure there is no race between the
bootup process and cron starting a normal run-cosmos process at the same
time.
The oexit() function is added to support exiting with a OK exit value
the same way eexit() is used to signal something is wrong.
This change also adds the systemd unit file that runs run-cosmos with the
new fleetlock-unlock argument at boot if fleetlock is configured.
While here fix indentation that was mixed between 3 and 4 spaces: it is
now 4 spaces everywhere.
The db-file, essentially providing reverse lookup of classes to host
names, is only used by some Nagios configuration instances and causes
continuing operational headaches in those ops-repos.
It should be kept/refactored to only apply to the monitoring hosts in
the cases where it is used, but we don't want any new ops-repos to use
it hence it should be removed from upstream multiverse.
