Allow for the use of multiple ssh keys

[meunierd]

Is your feature request related to a problem? Please describe.
Github only allows a deploy key to be used once, so effectively you can only use weblate with a single github repository (unless you're using https credentials).

Describe the solution you'd like
Allow for using multiple SSH keys with weblate, to enable one-per repository/project.

Describe alternatives you've considered
HTTPS is workable here but it involves creating spoof deploy accounts which is far from ideal.

You can also create user on GitHub to be used by Weblate, see https://docs.weblate.org/en/latest/vcs.html#vcs-repos-github

The proper solution is to switch to using GitHub App and authenticate access to repositories through it, see #1688 (comment)

The link in that comment seems to 404.

I've fixed that now, but it's not much useful for now - it does ask for the permissions, but Weblate still doesn't use the access tokens from it.

This issue has been put aside. Currently, it is unclear whether it will be ever implemented as it seems to cover too narrow use case or doesn't seem to fit into Weblate. Please try to clarify the use case or consider proposing something more generic to make it useful to more users.

We have repos in both bitbucket and github. Do I understand correctly, that we must use the same ssh key in weblate for both bitbucket and github?

[nijel]

Yes, right now Weblate has a single SSH key.
