The repo re-org has removed 'stx-' from the name of the repos
that are checked out from the manifest, so there is no
need for special prefix handling in tox to accomodate
differences with checking out using "repo" or "git clone".
With the addition of tsconfig to this config repo, it will
generate an intermediate .stestr folder if tox is run
in that subdir. This has been added to the top level
.gitignore file.
The required-projects for the zuul jobs have been
cleaned up and references to STX-PREFIX are removed.
