Introduce API microversion 2.88, which makes the following changes to
a number of 'os-hypervisors'. Specifically, the following fields are
dropped from both the '/os-hypervisors/detail' (detailed list) and
'/os-hypervisors/{hypervisor_id}' (show) APIs:
- current_workload
- cpu_info
- vcpus
- vcpus_used
- free_disk_gb
- local_gb
- local_gb_used
- disk_available_least
- free_ram_mb
- memory_mb
- memory_mb_used
- running_vms
In addition, the '/os-hypervisors/statistics' API, which provided a
summary of the above stats but for all hypervisors in the deployment, is
dropped entirely.
Finally, the '/os-hypervisors/{hypervisor}/uptime' API, which provided a
similar response to the '/os-hypervisors/{hypervisor}' API but with an
additional 'uptime' field, has been removed in favour of including this
field in the primary '/os-hypervisors/{hypervisor}' API.
A small tweak to 'tox.ini' that allows us to share some venvs is
included.
