We can check from the history[0], actually it doesn't matter if
gnocchi or panko is started first., so this check is unnecessary.
Also when i want to migration using native zuulv3, the enabled
plugins is in the alphabetical order, so this will caused can not
install devstack correctly.

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:

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.

For long running users of Ceilometer with heavy sample loads,
the index for samples can run out of numbers.  The int type only
allows over 2 billion samples to be loaded.  To allow a user
with database backed sample storage (postgres or mysql) to continue
to operate, we need to up the data type to BigInteger.

oslo.messaging replaced kafka-python to confluent-kafka [1], so instead of
adding the kafka-python to test-requirements the oslo-messaging[kafka]
should be used.

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.

do not build metrics off compute.instance.create.start as it
doesn't have enough information in it to push to Gnocchi. there is
an .end event that happens seconds later so .start event has little
value outside context of event.

we change fnmatch to regex for more useful regex comparison and it's
faster

not a complete fix as compute.instance.update also is missing host
value occasionally

Missing metadata in the libvirt domain xml for a nova instance would
cause ceilometer-compute to abort, leading to missing metrics for the
current and any subequent libvirt guests.

This commit puts a try/except AttributeError block around all the code
that is fetching attributes on the result of metadata_xml.find(...).

Zuul no longer requires the project-name for in-repo configuration.
Omitting it makes forking or renaming projects easier.

agent

(cherry picked from commit 935b53c9)

- remove list of notifications used for meters, it's not accurate
and is arguably of no value to an administrator even if it's
accurate. just list where the endpoints are and how to configure.
- remove comments about database connection, this means nothing
- remove libvirt comment, listing all services polled as these are
stated elsewhere and are just repeated.

- remove dup details on compute, central, ipmi already in data
collection
- remove hbase from panko support
- remove listing libvirt hypervisors, we only test kvm/qemu.
- remove generic listing of 'OpenStack Networking' meters. we already
have a measurements page for this
- remove user, roles, projects notes. we don't have api and it
means very little as is

this is all irrelevant or duplicated:
- dbreco.rst
  - duplicates supported databases in admin-guide
  - ceilometer to gnocchi section is old and deck doesn't really
    reflect current gnocchi. also, all ocata+ docs install
    gnocchi by default.
- custom.rst
  - duplicates telemetry-data-pipelines in admin-guide
  - dups best practices in admin-guide with shuffle option
- upgrade.rst
  - upgrade is just stop, upgrade, restart for each service
  - nothing is unique except notification agent with partitioning[1]
    and existing stuff doesn't address it.
