This middleware is added to ironic-lib so that it can eventually be
used by ironic and ironic-inspector as an alternative to noauth in
standalone environments.
This middleware is passed a path to a file which supports the
Apache htpasswd syntax[1]. This file is read for every request, so no
service restart is required when changes are made.
The only password digest supported is bcrypt, and the ``bcrypt``
python library is used for password checks since it supports ``$2y$``
prefixed bcrypt passwords as generated by the Apache htpasswd utility.
