Migrating to deployment manager, part 1 (#282)

* Migrating to deployment manager, part 1

This is a first step in migrating the gcp ref. arch. away from shell script to
Google's gcp deployment manager and ansible. Most of the resources is now
migrated, more complicated resources will be migrated later. Naming was redone
- before, it was possible to choose arbitrary name for almost any resource -
now it's done by changing the 'prefix'. This way, it should be possible to
deploy multiple clusters under single account by choosing different prefix.

* Fixed spelling
