Upgrade localstack (#1604)

* Upgrade localstack

* Fix the dynamodb integration tests

The new localstack version emulates AWS better, returning a consumed
capacity only when the request asks for it.

* Update the Sts integration test for the new localstack return values

* Update the route53 expectation for the listing endpoint

In the new localstack version, creating a zone automatically creates the
NS and SOA records for that zone, emulating what actually happens on
AWS.

* Switch to 3.0.0

* Skip bad test for now
