Currently if batch_polled_samples=True (default) then it will batch
up all samples of a poller into one message. This can be problematic
if the poller returns a large number of samples.

Since kernel v4.6, virtio balloon driver commit 5057dcd0f
introduced metric VIRTIO_BALLOON_S_AVAIL,
corresponding to 'Available' in /proc/meminfo.
Libvirt exposed this metric as 'usable'.
As 'Available' of meminfo is an estimate of how much memory
is available for starting new applications, without swapping.
It's a better metric for calculating memory_usage.

Curly quotes(Chinese punctuation) usually input from Chinese input method.
When read from english context, it makes some confusion.

Theses features doesn't work well, rate-of-change metrics can still
wrongly be computed even with Pipeline partioning enabled. Also backend
like Gnocchi offers a better alternative to compute them.
This deprecates these two features, to be able to remove them in a couple
of releases.

This metric has been removed in 2015 when the Ceilometer WSGI middleware has
been removed from this repository. The new ceilometermiddleware package does
not provide it.

since it is ceilometer's devstack plugin who enables/starts gnocchi
services, it is appropriate to also stop them during unstack phase.

It was mentioned "7 different transports", but there just shows 5
transports. I supplement 2 missing transports "zakar" and "https".

We can't create archive policies in publisher init because if it fail
because Gnocchi is not yet ready the publisher fail to load. Ceilometer
will work, but samples will go to nowhere.
This change creates/checks archive policies when we publish a sample for
the very first time. If that fail because Gnocchi is not ready, this
will just retry next time Ceilometer will publish samples.

This creates two archive policies "ceilometer-low" and
"ceilometer-low-rate" in Gnocchi. And use them to create metrics
in Gnocchi.
The archive policies settings can now be configured in
gnocchi_resources.yaml.
This requires upcoming release of coming
