Recommend qastaging.launchpad.net over staging.launchpad.net

[Hemanth V. Alluri]

When trying to create a test project on launchpad.net, a recommendation appeared in one corner of the page suggesting that I use staging.launchpad.net if I was testing. However, staging.launchpad.net does not support git repositories. In question #680828 (https://answers.launchpad.net/launchpad/+question/680828) Colin Watson suggested that I use qastaging.launchpad.net instead if I wanted to use git repositories and https://help.launchpad.net/API/Webhooks also talks about qastaging.launchpad.net but not staging.launchpad.net (for the same reason that git repositories are not suggested by staging.launchpad.net in the first place - so the git webhook target/object wouldn't exist in the first place).

Thus I propose replacing the suggestion to use staging.launchpad.net with a suggestion to use qastaging.launchpad.net instead.

We need to work out whether it's better to complicate the UI message (since it's when creating a project, so not intrinsically git-specific) or to add git support to staging. The latter isn't trivial of course (as well as a new backend deployment, it may require arranging to preserve git repositories across staging database restores, which are much more frequent than on qastaging), but it would certainly be convenient for other reasons.
