This was already fixed in 4889dc1814 but
we did not enforce this rule and reintroduced "bad" string
interpolations. This patch adds a hacking rule to prevent us from doing
this again in the future.

Glance was not supporting uwsgi deployment when we added periodic job
to prefetch images into cache. Later in ussuri uwsgi support was added
but we missed to implement periodic job to pre-cache the image.
This patch add this support for glance + uwsgi. For WSGI, we run the
prefetcher with an external lock, which makes sure that multiple API
workers will not attempt to cache an image at the same time. In this
case, if multiple workers attempt to run at the same time, only one
will grab the lock and do the work. When completed, the other worker
will grab the lock and either find all the work completed, or complete
new work that has been queued since the first one started.

This teaches glance-api how to do async threading things when it is
running in pure-WSGI mode. In order to do that, a refactoring of things
that currently depend on eventlet is required.
It adds a [wsgi]/task_pool_threads configuration knob, which is used
in the case of pure-WSGI and native threads to constrain the number
of threads in that pool (and thus the task parallelism). This will
allow tuning by the operator, but also lets us default that to just
a single thread in the backport of these fixes so that we can avoid
introducing a new larger footprint in the backport unexpectedly.

This refactors the task creation path to allow optional passing
of an admin-enabled ImageRepo to tasks. This will be used for
allowing import_image(method='copy-image') to update non-owned
image metadata during a copy.

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