AWS security groups are unique by name only by VPC (Restated, the VPC
and group name form a unique key).
When attaching security groups to an ELB, the ec2_elb_lb module would
erroneously find security groups of the same name in other VPCs thus
causing an error stating as such.
To eliminate the error, we check that we are attaching subnets (implying
that we are in a VPC), grab the vpc_id of the 0th subnet, and filtering
the list of security groups on this VPC. In other cases, no such filter
is applied (filters=None).
EC2 Security Group names are unique given a VPC. When a group_name
value is specified in a rule, if the group_name does not exist in the
provided vpc_id it should create the group as per the documentation.
The groups dictionary uses group_names as keys, so it is possible to
find a group in another VPC with the name that is desired. This causes
an error as the security group being acted on, and the security group
referenced in the rule are in two different VPCs.
To prevent this issue, we check to see if vpc_id is defined and if so
check that VPCs match, else we treat the group as new.
While from the documentation[1] one would assume that replacing
CAPABILITY_IAM with CAPABILITY_NAMED_IAM; this as empirically been shown
to not be the case.
1: "If you have IAM resources, you can specify either capability. If you
have IAM resources with custom names, you must specify
CAPABILITY_NAMED_IAM."

Previously, when the attributes of a GCE firewall change, they were ignored. This PR changes that behavior and now updates them.
Note that the "update" also removes attributes that are not specified.
An overview of the firewall rule behavior is as follows:
1. firewall name in GCP, state=absent in PLAYBOOK: Delete from GCP
2. firewall name in PLAYBOOK, not in GCP: Add to GCP.
3. firewall name in GCP, name not in PLAYBOOK: No change.
4. firewall names exist in both GCP and PLAYBOOK, attributes differ: Update GCP to match attributes from PLAYBOOK.
Current module fails when tries to assign floating-ips to server that
already have them and either fails or reports "changed=True" when no
ip was added
Removing floating-ip doesn't require address
Server name/id is enough to remove a floating ip.
This parameter was actually added in 2.0. It's just that the
documentation in previous versions of the module were wrong (it said the
name was "network" rather than "name.) I've renamed the parameter in
the documentation of prior versions so ansible-module-validate should no
longer think that this is a new parameter.
The module would raise a KeyError trying to find the save_config key
which is not present in the argument_spec. This was caused by the
check_args() function. Since the ios shared argument spec isn't used
the check_args function is not needed and has been removed.
