bitbake: toaster: enable SSH-based remote build support
We enable support for starting builds on remote machines through SSH. The support is limited to poky-based distributions. We refactor localhost build support and we update bldcontrol application tests to uniformely test the APIs of localhost and SSH build controllers.
