This patch combines 4 backports to try to fix the stable/train gates.

1. Fix gate job failures and py3 compatibility

- Fix incorrect type handling of secret payload in py3
  (it should be bytes instead of str by default)
- Fix py3 compatibility of test codes
- Update expiration date so that resources are created with valid
  expiration.

3. Zuul: port to native v3 job

Port the functional job to the native Zuul v3 format,
and remove a few old wrapper scripts which are not needed
anymore (the tests can be run locally through `tox -efunctional`
as well).

The original commit did also change the unit test job
to fit that branch, but it is not needed here.

4. Drop lower-constraints.txt and its testing

As discussed in TC PTG[1] and TC resolution[2], we are
dropping the lower-constraints.txt file and its testing.
We will keep lower bounds in the requirements.txt file but
with a note that these are not tested lower bounds and we
try our best to keep them updated.

This patch also fixes a broken test by updating the maximum
payload size to match the current maximum in Barbican. [3]

This patch also skips an additional broken test.  It will be
fixed in a separate patch.

Update the URL to the upper-constraints file to point to the redirect
rule on releases.openstack.org so that anyone working on this branch
will switch to the correct upper-constraints list automatically when
the requirements repository branches.

Until the requirements repository has as stable/train branch, tests will
continue to use the upper-constraints list on master.

We seem to be running into a coverage issue [1] in 4.0.  This patch
raises the lower bound of coverage to 4.1 to get the lower-constraints
target to pass again.

This commit was bulk generated and pushed by the OpenDev sysadmins
as a part of the Git hosting and code review systems migration
detailed in these mailing list posts:

http://lists.openstack.org/pipermail/openstack-discuss/2019-March/003603.html
http://lists.openstack.org/pipermail/openstack-discuss/2019-April/004920.html

Attempts have been made to correct repository namespaces and
hostnames based on simple pattern matching, but it's possible some
were updated incorrectly or missed entirely. Please reach out to us
via the contact information listed at https://opendev.org/ with any
questions you may have.

This is a mechanically generated change to replace openstack.org
git:// URLs with https:// equivalents.

This is in aid of a planned future move of the git hosting
infrastructure to a self-hosted instance of gitea (https://gitea.io),
which does not support the git wire protocol at this stage.

This update should result in no functional change.
