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.

When you comment all the elements in a YAML mapping, you end up with
None instead of an empty mapping, which can have bad side effect when
handling multiple environemnents. Let's handle that by ignoring the
latest None value.

(cherry picked from commit 2a8ce0d0)

This is a mechanically generated patch to complete step 1 of moving
the zuul job settings out of project-config and into each project
repository.

Because there will be a separate patch on each branch, the branch
specifiers for branch-specific jobs have been removed.

Because this patch is generated by a script, there may be some
cosmetic changes to the layout of the YAML file(s) as the contents are
normalized.

See the python3-first goal document for details:
https://governance.openstack.org/tc/goals/stein/python3-first.html

Remove tools/tox_install.sh, it breaks docs build and is not needed.

Due to Python buffering sys.stdin and sys.stdout, the read can be shown
before text prompt.

Encoding the path separators results in urls refused by by apache
with 404 unless AllowEncodedSlashes is turned on, which is not
the default.

The existing encoding of path separators seems unnecessary.

The gating on python 3.4 is restricted to <= Mitaka. This is due to
the change from Ubuntu Trusty to Xenial, where only python3.5 is
available. There is no need to continue to keep these settings.

Add optional arguments '--yes' or '-y' in osc cli `openstack stack
snapshot delete`. There is no judgement before use that cli
So propose to add it in case that we delete the snapshot unintentionally.

An upcoming release of pbr will require explicitly stating which
builders are requested, rather than defaulting to html and man. Head off
any potential impact this may cause by explicitly setting this
configuration now.

1.As mentioned in [1], we should avoid using six.iteritems to achieve
iterators. We can use dict.items instead, as it will return iterators
in PY3 as well. And dict.items/keys will more readable.
2.In py2, the performance about list should be negligible, see the
link [2].
