Title:
  Incorrect use of oslo.utils added

Status in python-keystoneauth1 package in Ubuntu:
  New

Bug description:
  There is a patch added in the ubuntu package to deal with
  datetime.datetime.utcnow() deprecation. It solves this by pulling in
  oslo.utils, which might normally seem to make sense in an openstack
  packaging context.

  However - there are two issues.

  The first is simple - it adds usage of oslo.utils without adding it as
  a packaging dependency. This makes the library not work when installed
  without manual installation of an additional unrelated and unexpected
  package. The simple fix to this would be to add an appropriate package
  dependency.

  The second is philosophical - the keystoneauth project is
  fundamentally opposed to the use of runtime dependencies on oslo
  libraries. The oslo libraries are designed for server applications,
  while keystoneauth is intended for lightweight client interations, as
  it openstacksdk which depends on it. It is directly against the stated
  design goals of the project to add the oslo.utils import.

  As such, it is highly recommended that rather than updating the
  packaging to add a dependency on oslo.utils, simply replace
  datetime.datetime.utcnow() with
  datetime.datetime.now(datetime.datetime.utc) which adds no further
  dependencies.

  I have only noticed this in noble - where this missing package
  actually caused an unrelated CI job failure. I don't know if it
  manifests elsewhere.
