x/pkgsite: add function to set up test queue

[julieqiu]

There are a couple of places in the code where we want to set up a queue for testing:

• internal/frontend/server_test.go: https://github.com/golang/pkgsite/blob/master/internal/frontend/server_test.go#L992-L999
• internal/testing/integration/frontend_test.go: TODO - add link

It would be useful to have a single setupQueue function for use in testing.

The link for where the code is duplicated within internal/testing/integration/frontend_test.go is https://github.com/golang/pkgsite/blob/master/internal/testing/integration/frontend_test.go#L205-L211

@julieqiu
May I give it a try?

[julieqiu]

@amarjeetanandsingh please do!

@julieqiu Can I work on this?

@julieqiu queue.InMemory seems to be working effectively as a test helper and to be invoked by no other than test code. Isn't it necessary to create another function?

[julieqiu]

Nope - this issue seems to be outdated. Thanks for taking a look!
