2.0.1 "Adaptations"

This release contains a few small improvements and fixes for upcoming bodhi
server behaviour changes:

The OpenID endpoint for logging into bodhi servers will be deprecated with bodhi
6.0 servers, but will remain available under a different URL for now. The
primary method of authentication will be OpenID Connect, which is not going to
be supported in the fedora crate anytime soon, as it does not look like it
will support headless authentication, but will require the user to sign on via a
web browser window to retrieve an authentication token. With version 2.0.1 of
this crate, the authentication method was changed to explicitly use the
deprecated OpenID endpoint, until OpenID connect support can be implemented in a
way that works for this crate and its users.

Additionally, bodhi servers will no longer include the composes field when
serializing Release objects. As a result, the struct field has been marked as
deprecated, but otherwise it remains the same for backwards compatibility.
However, because JSON server responses will no longer include this field, it
will always contain a value of None, and should no longer be used.

The changes since 2.0.0 also include additions to the test dataset and
test suite that cover the latest Fedora releases:

• remove Fedora 33 and EPEL-6 from the lists of active releases
• add missing tests and test data for Fedora 36 and 37 releases
