    Allow Swift middleware to be set via a variable

    This patch allows the swift-proxy pipeline to be adjusted via a variable
    "swift_middleware_list", which can be amended to add additional
    middleware as required.

    The default remains the same - which is to include the default pipeline
    when using keystone.

    Additionally the logic around whether "authtoken" or "tempauth" are
    enabled was changed to check if these are set in "swift_middleware_list"
    without requiring a separate variable. Variable "swift_authtoken_active"
    was removed as it is no longer required.

    Tempest object storage settings were adjusted to work with the default
    list of enabled discoverable_apis for object storage. Container syncing
    was also turned into a variable based on the object storage default.
