* Fix ec2_vpc_vgw broken tests
Add waiter function to wait for API to report detached vgw is available.
Also catch extra error code in attach retry as EC2 sometimes reports that
the vgw is available several seconds before permitting the attachment.
Fixes: #53185
* Re-enable ec2_vgc_vgw test target
* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.
* Rebalance Windows tests with another group.
* Stabilize ec2_vpc_vgw and ec2_vpc_vpn so tests for ec2_vpc_vpn_facts in PR 35983 can be run in CI
* Add updated placebo recordings
* ensure find_vgw uses the virtual gateway id if available
Add AWSRetry.jittered_backoff to attach_vpn_gateway to deal with errors when attaching a new VPC directly after detaching
Add integrations tests for ec2_vpc_vgw
