Fix Trove CI jobs

Changes to get jobs working

1) After [1] devstack no longer changes the ownership of the whole
   /opt/stack tree to the stack user unconditionally. Switch to the
   stack user when running integration test.

2) Add bindep.txt file[2]. The default fallback file is not installed
   anymore and therefore a bindep.txt file is needed to add install
   additional packages.

3) Use trovestack script rather than devstack to build image so many
   global variables could be used for consistency. By default, devstack
   won't build image.

4) Remove the tools/test-setup.sh as it is not used any more.

5) Instance upgrade test keeps failing in CI for some reason, although
   it's always passed on my local environment. In order not to block
   other patches, skip the instance upgrade tests temporarily.
