Add RSpec helper routines

[ahelsing]

Writing RSpecs is a pain.

Investigate adding some routines to make this easier for experimenters.

[ahelsing]

Possibilities include

• script to run an RSpec through rspeclint, and/or other sanity checks
• routine to convert an Ad to a request, putting in comments and FIXMEs in places where the experimenter needs to do something
• routine to convert a manifest to a request, as above
• routine to 'update' an old request RSpec so it can be re-used
  • generate/expires tags changed
  • compare to a recent Ad to check availability
  • ?

Note I'm not currently suggesting routines that would essentially take an unbound request and make it bound, graphical tools, etc

Replying to ahelsing:

- script to run an RSpec through rspeclint, and/or other sanity checks

The method validate_rspec() (and it's helper method rspeclint_exists()) for running rspeclint on an RSpec is in gcf/src/geni/util/rspec_util.py

There are various other RSpec manipulation utility functions in this file. (That said, the file could probably use a little cleanup and refactoring.)
