Implement gcloud_producer for bm-tools

bm-tools works via "Machine" objects, which are front
objects for actual virtual or physical machines. glcoud_producer
produces machines on GCP using the `gcloud` tool.

Included are:
- GCloudProducer - the class producing machines
- MockGCloudProducer - class for mocking GCloudProducer.
- tests using the mock
- test data as .json files. Code to generate this test data may be
included in a follow up.
