* Add AWSRetry decorator to ec2_vpc_nacl
* Also add a decorator to ec2_vpc_nacl_info to catch things like API rate limit errors.
* add double-removal integration tests to make sure things don't get too slow
* Fixup retry usage for _info
* Simplify changed logic when modifying a NACL
* tweak error message
* Move EC2 networking objects into network-policy.json
* ec2_vpc_nacl: Add integration tests
* ec2_vpc_nacl: Migrate tests to use module_defaults
* ec2_vpc_nacl: (integration tests) Add missing AWS permissions
* ec2_vpc_nacl: (integration tests) Update tests for ipv6 support
* ec2_vpc_nacl: Migrate to AnsibleAWSModule
* Fix sanity tests for ec2_vpc_nacl and ec2_vpc_nacl_info
* ec2_vpc_nacl_info: Migrate to AnsibleAWSModule
* ec2_vpc_nacl_info: (integration tests) Rename from ec2_vpc_nacl_facts to ec2_vpc_nacl_info and add a test using a filter (by tag)
* Pick availability zones dynamically
Rather than assuming that AZa and AZb always exist (they don't), query to find out which AZs we have available first
* Test that the NACLs we get back are actually the *saml* NACL rather than duplicates/delete remove
* Cleanup IPv6 tests a little.
Note: IPv6 support for ec2_vpc_nacl not complete yet.
This provides the initial framework, and should ensure things don't start exploding when support is added.
* Removing subnets by name from a NACL *is* now supported
* Fix ec2_vpc_nacl return documentation
