imap-backup with email-oauth2-proxy support in a container about imap-backup HOT 2 OPEN

Thanks @mcrosson

This looks really interesting. I had been musing about how to ease the dual setup of imap-backup and email-oauth2-proxy and this looks like a good start.

I would imagine that this would become another container build that would be done on top of the existing "minimal" container

from imap-backup.

I have the setup running via cron and it's been quite stable. The only 'problem' is if you need to do a full auth for email-oauth2-proxy. The interactive bit it has on initial login needs an interactive terminal which kind of forces you to re-run the container interactively with email-oauth2-proxy as a foreground task to do the auth. Once the auth is good and not prompting, email-oauth2-proxy can be a background task (I used s6-overlay for this purpose).

I did set things up to extend the 'minimal container' and to preserve the environment vars that are needed by ruby for running imap-backup without ruby errors.

If you'd like I can pack up my code as a zip and post it here. The paths on the gist are a bit messy and deep due to the way s6-overlay works.
