[Feature Request] add unique cookie prefix or allow setting

[gen-angry]

Hello,

I am running this along with a few dozen other containers on a small home server with podman under one IP (using different port numbers for each service). It works pretty well aside from one issue: session cookie names often conflict causing frequent log outs.

wallabag uses generic names "REMEMBERME" and to a lesser extent "PHPSESSID". Would it be possible to append a unique prefix to the session ID cookie name (ie: 'wallabag_REMEMBERME') or allow us to add a prefix using an environment variable?

Thank you :)
