iLO driver generates public tempurls for vmedia

[Jacek Tomasiak]

iLO driver generates various images on the fly and uploads them to Swift. TempURLs are then used for mounting those images as vmedia in iLO. The default SwiftAPI client uses 'public' interface and it is passed on to the TempURLs (on ironic side).
The problem is that to make "iLO Scripted Media URL" work, the URLs need to be accessible from iLO. In some setups, public URLs are not accessible from iLO network.

    Allow Swift endpoint override

    Swiftclient uses public endpoint by default. Ironic uses the base URL
    from Swift connection to build TempURLs for generated images.
    Some drivers (e.g. iLO) use those TempURLs to mount images as vmedia.
    With public URLs it will fail if the BMC doesn't have access to the
    public network.

    This change introduces an option to explicitly set the endpoint URL
    used for Swift.

    This is a stable-only change as the problem is fixed by refactoring
    changes in later releases. This is the only version where Ironic uses
    public Swift endpoints and there is no option to override this.
