Support docker aws regions

[pweil-]

The region list in the s3 driver is out of date. We are missing us-east-2. The upstream also does not support ca-central-1 - it needs to be added and rebased into our dependency.

I had to add the following to Kube related items for each release:

3.3 to add missing support for the following: ap-south-1, ca-central-1, us-east-2

3.4 to add missing support for the following: ca-central-1, us-east-2

We should make sure that has parity.
