fix(gce): update to new path for example userdata
fix(scheduler): send environment to the process
fix(tests): check for immovable response

"Deis" in "Powered by Deis" is configured by an environment variable
called $POWERED_BY. We should not be checking for Deis, as it can be
defined as something else.

feat(contrib): add PREFIX option to digitalocean script

When provisioning new nodes, they are prefixed with a name of "deis-$i",

the name with something other than "deis" such that we can discern
between different clusters on the same DO account.
