* Allow idempotent use of ec2_ami_copy
When `tag_equality` is set true, use tags to determine
if AMIs in different accounts are the same, and don't
copy the AMI twice if they are the same.
Use AnsibleAWSModule and make imports more consistent
with other modules
* Update version added
* More code review changes
* Review changes - Recommended way to start EC2 connection
* Remove boto usage from boto3 modules
* Remove region checking
boto3_conn now takes care of region checking and handles NoRegionError
exceptions with a standard message
boto3_conn also takes care of other connection exceptions too.
* Document boto3 as a requirement for ec2_eni_facts
* ec2_ami_copy.py: Fix WaiterError handling.
Change suggested by Adam Johnson at https://github.com/ansible/ansible/issues/26971
* ec2_ami_copy.py: WaiterError: fail_json: add exception parameter.
* ec2_ami_copy.py: import traceback
Set encrypted to default False, rather than None
Otherwise you get:
```
Invalid type for parameter Encrypted, value: None, type: <type 'NoneType'>, valid types: <type 'bool'>)
```
