pip 23.1 removed the "setup.py install" fallback for projects that do
not have pyproject.toml and now uses a pyproject.toml which is vendored
in pip [1][2]. pip 24.2 has now deprecated a similar fallback to
"setup.py develop" and plans to fully remove this in pip 25.0 [3][4][5].
pbr supports editable installs since 6.0.0
pip 25.1 has now been released and the removal is complete.
by adding our own minimal pyproject.toml to ensure we are using the
correct build system.
This change also requires that we adapt how we generate our wsgi
entry point. when pyproject.toml is used the wsgi console script is
not generated in an editbale install such as is used in devstck
To adress this we need to refactor our usage of our wsgi applciation
to use a module path instead. This change does not remove
the declaration of our wsgi_scrtip entry point but it shoudl
be considered deprecated and it will be removed in the future.
To unblock the gate the devstack plugin is modifed to to deploy
using the wsgi module instead of the console script.
Finally supprot for the mod_wsgi wsgi mode is removed.
that was deprecated in devstack a few cycle ago and
support was removed in I8823e98809ed6b66c27dbcf21a00eea68ef403e8

Currently we are using `instance` label to query about host metrics to
prometheus. This label is assigned to the url of each endpoint being
scrapped.
While this work fine in one-exporter-per-compute cases as the driver is
mapping the fqdn_label value to the `instance` label value, it fails
when there are more that one target with the same value for the fqdn
label. This is a valid case, to be able to query by fqdn and do not
care about what exporter in the host is providing the metric.
This patch is changing the queries we use for hosts to be based on the
fqdn_label instead of the instance one. To implement it, we are also
simplifying the way we check the metric exist for the host by converting
prometheus_fqdn_instance_map into a prometheus_fqdn_labels set
which stores the list of fqdn found in prometheus.
