In addition to the standard `endpoint` parameter, fog-aws also supports:

- `host`
- `scheme`
- `port`

If consolidated object storage settings are used with these parameters,
Workhorse will not receive the right endpoint. The S3 Workhorse client
will attempt to use the default AWS endpoints
(e.g. `bucket.s3.amazonaws.com`) instead of the custom host.

Since fog-aws has some special defaults and logic that maps regions to
endpoints, we drive the endpoint by looking at a sample URL.
