Press 'h'/'?' to get troubleshooting information

[waldekmastykarz]

We should offer support for troubleshooting most common issues with using Dev Proxy:

• no requests intercepted
• requests intercepted but passed through
• SSL error in the app when using proxy

Users should be able to invoke this information by pressing 'h' or '?' (which one is more intuitive?).

Questions to decide:

• which hotkey to use
• should the information be available in the terminal or as a link that points to our docs

[garrytrinder]

h would be simpler as it's only one key vs a combination, but ? feels right to me.

I think the information should be available in the terminal. Once the help information is displayed we should make sure that no request logs are added to the output IMO.

That would require us to have a way to pause and resume proxy which we currently don't have. Also, we need to see if we can provide the necessary debugging steps in a concise way that fits in the terminal.
