Description of problem:

The inline documentation for creating an EC2 compute resource via CLI claims that a URL is a requirement for Libvirt, Ovirt and Openstack but it does not mention EC2. Based on this, REGION should be the argument for EC2 but running the CLI fails unless you pass URL

[root@qetello02 ~]# LANG=en_US hammer -v -u admin -p changeme --output csv compute-resource create --help
