Fixup for SuSE and openSuSE.

Account for differences in packages names across RHEL/CentOS
and SuSE/openSuSE.
If an AWS account does not have a default subnet in their VPC configuration, then creating instances in that VPC will not automatically provide a public IP/DNS. Boto added this functionality in 2.13.0 (NetworkInterfaceSpecification.associate_public_ip_address).

This change adds assign_pubic_ip as a parameter to the ec2 module, ensuring that it is not set to one of BOOLEANS_TRUE if vpc_subnet_id is not also set, and if Boto is less than 2.13.0.
Exit 0 with no matched hosts

And also print to stdout not err

This lines up with how ansible-playbook will exit. 0 in the case of no
matched hosts. This makes it easier to script ansible commands w/
variable iventory input which may or may not have an entry for the
specific ansible task being scripted. No matched hosts is acceptable,
but matched hosts w/ failures is not.
Added `-y` flag to `query_package`
