Subject: Make cycle.sh usable for build/deploys onto target (eg from chroot)

This re-write runs all of the system-version-manager commands on
the target cluster via ssh, so in addition to self-upgrades,
cycle.sh can now be used to upgrade a target device (eg a devboard)
while working in Baserock VM or chroot
