Reviewers: mp+212978_code.launchpad.net,

Message:
Please take a look.

Description:
provider/manual: support all architectures

Change SupportedArchitectures to return all
architectures supported by Juju. Otherwise
we will not be able to provision machines
of architectures other than the bootstrap-host.
