Optimize config loading messages

As kinda discussed here #3090, the messages regarding loading the
configuration files is a bit strange or unclear. There have been some
other reports regarding this in the past, but wasn't that big a of a
deal.

But to make the whole process it bit more nice, this PR adjusts the way
it reports issues and some small changes to the messages to make it all
a bit more clear.

- Do not report a missing `.env` file, but only send a message when using one.
- Exit instead of Panic, a panic causes a stacktrace, which isn't needed
  here. I'm using a exit code 255 here so it is different to the other
  exit's we use.
- Exit on more issues, since if we continue, it could cause
  configuration issues if the user thinks all is fine.
- Use the actual env file used in the messages instead of `.env`.
- Added a **INFO** message when loading the `config.json`.
  This makes it consistent with the info message for loading the env file.

Resolves #3090
