Testing environment tries to install irods packages in database container when --project-name argument has underscores

[SwooshyCueb]

We have a few functions in context.py that try to pull information from container names by splitting them by underscores:

irods_testing_environment/irods_testing_environment/context.py

Lines 147 to 175 in 615a2e2

	def project_name(container_name):
	"""Return the docker-compose project name based on the `container_name`.
	NOTE: docker-compose "sanitizes" project names to remove certain special characters, so the
	`--project-name` provided to `docker-compose` may be different from the project name used
	when constructed the name of the image(s) and container(s).
	Arguments:
	container_name -- the name of the container from which the project name is extracted
	"""
	return container_name.split('_')[0]
	def service_name(container_name):
	"""Return the docker-compose project service name based on the `container_name`.
	Arguments:
	container_name -- the name of the container from which the service name is extracted
	"""
	return container_name.split('_')[1]
	def service_instance(container_name):
	"""Return the service instance number based on the `container_name`.
	Arguments:
	container_name -- the name of the container from which the service instance is extracted
	"""
	return int(container_name.split('_')[2])

However, the --project-name argument to the runner scripts allows the user to specify a string that will, among other things, be used as the first part of the container names. If the user specifies a name with underscores, these functions will return the wrong values. This causes the testing environment to attempt to install irods packages in the database container, which will fail under most circumstances due to distro mismatch.
