- Don't hardcode the job ID - it makes Galaxy mapping tricky, seems to be not reason to anyway.
- Don't assume tool execution container has bash.
- Rev to this version of Pulsar.

Testing for Kubernetes installed with Docker for Mac:

- Run `make build-coexecutor-container`
- Install and start rabbitmq on the localhost with Homebrew.
- PULSAR_TEST_INFRASTRUCTURE_HOST=docker.for.mac.localhost  PULSAR_TEST_FILE_SERVER_HOST=0.0.0.0 PULSAR_RABBIT_MQ_CONNECTION='amqp://guest:guest@localhost:5672//' nosetests test/integration_test.py:ExternalQueueIntegrationTests.test_integration_kubernetes

Can now build a Docker image and run test suite including MQ, run as real user, DRMAA, CLI torque stuff, etc....
