Provide path for config file in command-line invocation

[gbtb]

Proposed Feature

Hello.

I'd like to be able to provide path to configuration file into command-line invocation, like dotnet monitor --config /my/settings.json collect. According to documentation it's not supported atm.

I think it will be more convenient to end-user then placing file into pre-defined location or pass config through env vars. It will also allow to change settings more easily and store multiple settings files with git.
