[Feature] Log auto-archive policy

[barthofu]

Feature

We should define a policy for auto-archiving logs.

Format

We'll go with the gzip format as it is the easiest to use with node.js both on Windows and Linux with the built-in library zlib.

Frequency / treshold

We have two options for this :

1. Each x time (e.g: one archive per day)
2. At x size (e.g: 1MB limit per file)

For the sake of the retention policy and human accessibility/readibility, we've decided to go for an archive per day (not configurable as for now).

Retention policy

Finaly, a retention policy could be configured with a day count as input (e.g: keep only the logs of the 30 last days).
