Add documentation for required parameter name to quantum_subnet
Adding ansible_shell_type and basic environment construction on it

Previously we assumed the shell on the target systems were 'sh'-

strings. This patch corrects that by basing the target shell type
on the DEFAULT_EXECUTABLE setting, which can be overridden on a
per-host basis using the inventory variable 'ansible_shell_type'.
