Script creation of the spec test environment to automate recording new VCRs

[agrare]

Some providers have scripts which automate creation of a new spec test environment making it simple to re-record vcr_cassettes when necessary.

Pointing this script to an empty GCE project with proper credentials should create all objects used by the spec tests, these specs should only check for inventory by name not ems_ref (since this can change), ideally re-recording twice shouldn't change anything in the specs.
