This is to deal with the problem that it makes sense to have a separate
passsword for encryption keys and the admin provisioner. It is currently
not possible to control this via the docker env flags so add this
workaround for now.
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.
While we already support setting a healthcheck timeout it probably
makes sense to be able to control how long we wait for a
fleetlock_lock() or fleetlock_unlock() call. This becomes important if
only running cosmos once a night or something like that. In that case we
you probably want to give a physical machine more than than 1 minute to
complete a reboot etc.
This can now be controlled by setting fleetlock_lock_timeout and
fleetlock_unlock_timeout in /etc/run-cosmos-fleetlock-conf. Keep in mind
that while it can make sense to increase the time for taking a lock,
releasing a lock should always be fast (either you have it and release
it, or you dont have it and it is a no-op) so setting a long unlock
timeout should probably never be done.
Since we also potentially wait the unlock timeout at boot (if the
fleetlock server is broken etc) that is another reason to keep it
short. The default 1m is probably OK for most uses.
