x/build/cmd/gopherbot, x/build/maintner: handle non-Go Github issue repos like gddo

[kevinburke]

https://github.com/golang/gddo has a separate issue tracker, but gopherbot ("CL X mentions this issue") can only comment on golang/go repos.

We might also need to update parseGithubRefs in maintner/github.go but at first look at that function makes it seem like it is capable of doing the right thing.

[kevinburke]

We'd need to update this call in cmd/gopherbot/gopherbot.go:

func (b *gopherbot) initCorpus() {
	ctx := context.Background()
	corpus, err := godata.Get(ctx)

to fetch the gddo Gerrit and Github repositories as well, then modify the logic in the "CL X mentions this issue" function.

This might be a good issue for a new contributor.

subrepo oauth2 is being pointed to in a hyperlink on the above CL

the intended issue was however a go repo one and not a subrepo issue

factually a subrepo was pointed to in a hyperlink of a CL

I believe this is done, at least on the x/build/maintner side. In the *maintner.Corpus (from x/build/maintner/godata), the issue tracker of golang/gddo GitHub repo has 96 open issues and 304 closed issues right now. That matches the counts at https://github.com/golang/gddo/issues exactly.

Is there anything else that needs to be done here @kevinburke?

Edit: I think I misunderstood what this issue was about. It's not about just adding support for non-Go issue trackers (which is done), but rather for supporting links to those in context of gopherbot. Sorry.

Was this an isolated occurrence?

I don't know what volume of data is being dealt with, but CLs might be searched for links pointing to subrepos.
