The AWS region to connect to. The configured `:region` is
used to determine the service `:endpoint`. When not passed,
a default `:region` is search for in the following locations:
* `Aws.config[:region]`
* `ENV['AWS_REGION']`
* `ENV['AMAZON_REGION']`
* `ENV['AWS_DEFAULT_REGION']`
* `~/.aws/credentials`
* `~/.aws/config`

option(:endpoint, doc_type: String, docstring: <<-DOCS) do |cfg|
The client endpoint is normally constructed from the `:region`
option. You should only configure an `:endpoint` when connecting
to test endpoints. This should be avalid HTTP(S) URI.
