* Update Shippable integration test groups.
* Update integration test group aliases.
* Rebalance AWS and Azure tests with extra group.

* Added changelog fragment
* Divide Windows integration tests into 2 groups.
* Support `none` for `--changed-all-target`.
* Run 2 separate Windows groups on Shippable.
* Only run smoketest and minimal for the group1 job.
