Fix Trove CI jobsstable/stein

This is a combination of 2 commits, both are necessary to fix every CI
issue:

1. 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.

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.

6) Don't use master branch python-troveclient for stable branch Trove.

[1] https://review.opendev.org/203698
[2] http://lists.openstack.org/pipermail/openstack-discuss/2019-June/006888.html

Conflicts:
	devstack/plugin.sh
	integration/scripts/functions_qemu
	integration/scripts/trovestack
Note(elod.illes): bullet 3. skipped from backport as it is not a necessary
patch I think.

2. Use opendev.org instead of git.openstack.org

After moving to opendev.org, the following command fails when building
the Trove guest image:

curl -o /opt/stack/devstack/upper-constraints.txt \
  'https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=master'

https://opendev.org/openstack/requirements/raw/branch/master/upper-constraints.txt
should be used instead.

Other places using git.openstack.org are also changed.
