* AnsibleAWSModule related cleanup - s3_bucket
* Add extra information to s3_bucket timeout failures, it's possible the comparisons are doing something weird...
* Move Bucket Encryption boto support logic into the pre-flight checks
* Use the built in required_by logic
* Rework s3_bucket integration tests
* Add a retry around put_bucket_encryption
s3_client.put_bucket_encryption is occasionally dropped on the floor
by Amazon add some logic to retry s3_client.put_bucket_encryption call
* Catch OperationAborted and retry, it is caused by a conflicting change
still being in progress. (For example an Encryption setting applying)
* Make sure we don't explode if the botocore version's too old
* Review tweaks
* s3_bucket: Allow empty encryption_key_id with aws:kms to use KMS master key
* Add idempotency check and cleanup example, dont require encryption_key_id
* Add purge_tags to s3_bucket to allow preservation of existing tags
Adding `purge_tags` with default `True` to maintain existing behaviour
allows users to set it to `False` to preserve existing tags
Fixes#29366
* s3_bucket: Add further tests and improve tag handling further
Additional tests for purge_tags: False suggested some incorrect
logic and thus further improvements
Increase wait timeout on bucket deletion as it wasn't always completing
in the default 100 seconds
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
