Make script to compress logs on server

[smessie]

Logging in production was done to /mnt/dsashare/fireball/logs. Those logs were then rotated to /mnt/dsashare/fireball/logs/archive and took up some storage. You want to compress these with for example gzip. The compressed logs that you can find in the folder are because of manual compression.
I see that since 2021-01-02 no more logs are send here. The docker now has a volume that is mount onto the log folder. Logs can now be found here /var/lib/docker/volumes/blokat_backend_logs/_data. The archived folder now has 5.3GB of raw archived logs. This should be compressed.

Currently disk usage of this is not a problem yet, but to be prepared following idea:
Create a manual zip script to compress logs from time to time. The script can then filter all log files so that already zipped files are not recompressed.
