In Rocky multiple backend support is added as experimental feature. In
order to take advantage of this feature it is decided to deprecate
work_dir and node_staging_uri configuration options
and reserve two filesystem stores 'os_glance_tasks_store' and
'os_glance_staging_store', which can be used to get rid of initializing
store via internal functions.
These internal stores are considered "reserved stores" by Glance.
For the time being, these are hard-coded as filesystem stores. The
store prefix 'os_glance_' is reserved for internal Glance use and
the glance-api service will refuse to start if a store with this
prefix is included in the enabled_backends config option in
glance-api.conf.
NOTE: Because there are no sensible default values for the location
of the datadir for each of these stores, the operator must define
'os_glance_tasks_store' and 'os_glance_staging_store' in
glance-api.conf configuration file as shown below.
[os_glance_tasks_store]
filesystem_store_datadir = /var/lib/glance/tasks_work_dir/
[os_glance_staging_store]
filesystem_store_datadir = /var/lib/glance/staging/
Each filesystem store must have a unique datadir.

This change will allow glance services to run on Windows, using
eventlet wsgi for API services.
This change will:
* avoid monkey patching the os module on Windows (which causes Popen
to fail)
* avoiding unavailable signals
* avoid renaming in-use files or leaking handles
* update the check that ensures that just one scrubber process may
run at a time. We can't rely on process names as there might be
wrapper processes that have similar names (no she-bangs on Windows,
so the scripts are called a bit differently). We'll use a global
named mutex instead.
A subsequent change will leverage Windows job objects as a
replacement for process groups, also avoiding forking when spawning
workers.
At the moment, some Glance tests cannot run on Windows, which is
also covered by subsequent patches.

In Python 3.7, "async" is a keyword. To prevent it from
conflicting, rename the async package to async_.
