Adding Github backend

[EduardGomezEscandell]

Reports bugs as Github Issues to a given repository. This is done with Ubuntu WSL in mind, but can be easily adapted for other purposes.

Authentication

Uses Github's Device flow:
https://docs.github.com/en/developers/apps/building-oauth-apps/authorizing-oauth-apps#device-flow

This means that the user is given this message:

Input the following code in your browser:
URL: https://github.com/login/device
Code: B45A-7491

And this is used to authenticate.

Some work left to do:

$ ubuntu-bug python3

First, it fails to find attach_casper_md5check

ERROR: hook /usr/share/apport/general-hooks/ubuntu.py crashed:
Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/apport/report.py", line 241, in _run_hook
    symb["add_info"](report, ui)
  File "/usr/share/apport/general-hooks/ubuntu.py", line 84, in add_info
    apport.hookutils.attach_casper_md5check(report,
AttributeError: module 'apport.hookutils' has no attribute 'attach_casper_md5check'

Afterwards, when clicking on the github link, it doesn't open, and it shows:

(apport-gtk:1416): Gdk-WARNING **: 09:23:37.764: Server is missing xdg_foreign support

(apport-gtk:1416): Gtk-WARNING **: 09:23:37.765: Unable to show 'https://github.com/login/device': Operation not supported

I can still acces it via Right click > Copy link address.

Finally, the link to the issue, automatically openened at end, is opened via /usr/bin/lynx. I'd like to open it from Windows' side to use Windows' default browser.

Better use requests (it support proxies and stuff). To make the test happy, you have to add python3-requests to .github/workflows/ci.yaml.

Force-pushed after rebasing to catch up to main branch

Status

It works, there as some UX improvements possible but I believe they are best left for a future PR. These include:

• Opening links on the Windows browser
• Making the login code copy-paste-able.

Blocking aspects

File etc/apport/crashdb.conf uses a Github App ID linked to my account to talk to the Github API:

apport/etc/apport/crashdb.conf

Lines 27 to 34 in 7a9f870

	'ubuntu-wsl': {
	'impl': 'github',
	'repository_owner': 'EduardGomezEscandell', # TODO: Change to an Ubuntu account
	'repository_name': 'GithubAPI', # TODO: Change to "WSL"
	'github_app_id': 'a654870577ad2a2ab5b1', # TODO: Give App ownership to a Canonical github account
	'labels': ['apport'],
	'distro': 'ubuntu wsl'
	},

This has to be changed to an Ubuntu account before this PR is merged (I'm on it)

Closing this PR because this work was taken over in #26.
