Add support for Mongo TLS & Atlas

[mkrle]

Description:

I have added flags for TLS (tls) and authSource to the MongoDB URLs. The TLS flag is set to true depending on the MONGO_TLS variable. authSource is always set to admin.

Benefits of this PR and context:

This PR will do the following:

• Optionally enable TLS for MongoDB (required for Atlas)
• Fix authentication issues when using Atlas as MongoDB backend due to database name being passed as defaultauthdb parameter

How Has This Been Tested?

I have tested with not defining MONGO_TLS variable and haven't noticed any change in behaviour. It would be good if we could get more volunteers to test.
My test environment was linux (arm64) docker with Atlas as MongoDB backend.

hi,
unfortunally it doesn´t work without modifications.
By using authSource=unifi it works.
I will describe it in details at #9

[mkrle]

Got your point @tobiasfaust. I've updated the PR to set authSource to MONGO_DBNAME by default, and then allow others (e.g. Atlas users) to set it to admin using MONGO_AUTHSOURCE variable. Please let me know if it works in your case.

hi @mkrle, it works perfectly right now.
I hope this PR would be merged as soon as possible into the master branch.

Done. Also squashed the commits as they were growing in number. Thanks a lot for the feedback!

Other than the changelog fix looks fine and I'll be happy to approve it.
