Add option to save log to text

[nyalldawson]

Add a general "save" button which saves all requests (and response) details to a txt file (or json?). We could include QGIS debugging info at the start, e.g. QGIS version.

Would be useful for QGIS bug reports -- we could request network activity logs from users with private WMS/WFS/etc servers who are hitting errors.

To do this we should implement the visitor pattern - and have a visitor for "save to txt", "save to json", etc...

Wondering how to produce POST calls within QGIS. I've started exploring the code to dump requests to JSON but I'm unable to find a case to produce some POST requests and I know the case exists e.g https://github.com/rduivenvoorde/qgisnetworklogger/blob/master/Logger/model.py#L96.
Do you know a good use case to make POST in QGIS, so I could see them in your tool and debug to export to JSON? Thanks

FIY, do not hesitate to comment on my sample https://gist.github.com/ThomasG77/947212b91b57e69e25982dadb77afcf6 (it writes all lines to JSON)
We can discuss how you would see integration of this script within the UI?
