Julia Kreger d6b339ba34 Automatic zstd detection and decompression...
... for conductor downloads.

The issue is we don't have the underlying library for requests to do
Zstandard decompression, but userspace tools are common in linux
distributions, and opportunistically we will try to detect, and
de-compresse artifacts.

Zstandard is popular for compression of artifacts in container
registries.

Adds the capability for Ironic's conductor to detect Zstandard
compressed content and to automatically decompress the files
to enable image format detection and conversion.
This is due to use of Zstandard compression upon artifacts stored
in container registries is a popular practice, and can be disabled
using the ``[conductor]disable_zstandard_decompression``
configuration option.
