Change logging format

[felixschndr]

In opinion the logging format of multi-mcp is pretty difficult to read because of the formatting:

It does not stretch the message across the whole screen.

I think this is because of the rich logging formatter. Maybe this could be exchanged through something more normal. You might take a look at this logger which produces a much more readable format.
