API Keys read from environment variables (#1075)

* Update client keys to use environment vars

* Extra logging to assist with debugging

* Add other files to test target (temporary solution)

* Update Project Target References

* Add arguments and share scheme

* Disable failing FBSnapshot tests

* If at first you fail, wait 20 minutes for a build and then try again

* Update test to also ensure it's not using the template keys

* Update gitignore

* Remove intentional failing test

* revert pod changes

* revert podfile
