Merge lp:~thomir-deactivatedaccount/adt-cloud-worker/trunk-inine-uci-nova into lp:adt-cloud-worker

[Thomi Richards]

Inline the uci-nova ssh setup script.

Inline the uci-nova ssh setup script. This MP changes the code to point to the new ssh setup script, but doesn't change the contents of the ssh setup script at all (that will happen next).

[Francis Ginther (fginther)]

Approve. This is consistent with the same change performed for lp:core-image-tester.
