Diun v3 to v4

Timeout value as duration

Only accept duration as timeout value (10 becomes 10s)

Configuration transposed into environment variables

All configuration is now transposed into environment variables. Take a look at the documentation for more details.

DIUN_DB env var has been renamed DIUN_DB_PATH to follow environment variables transposition.

All fields in configuration are now camelCased

In order to enable transposition into environmental variables, all fields in configuration are now camelCased:

• notif.mail.insecure_skip_verify > notif.mail.insecureSkipVerify
• notif.rocketchat.user_id > notif.rocketchat.userID
• watch.first_check_notif > watch.firstCheckNotif
• ...
