add a debug log saying "mapping to vpce"

Review Comment:
so this is going to match on anything with .vpce. isn't it? I think it
should include amazonaws.{com,com.cn} at the end so if someone ever sets up an
internal host called vpce there's no confusion.
> S3A region logic to handle vpce and non standard endpoints

> Key: HADOOP-18938
> URL: https://issues.apache.org/jira/browse/HADOOP-18938
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Ahmar Suhail
> Priority: Major
> Labels: pull-request-available
>
> For non standard endpoints such as VPCE the region parsing added in
> HADOOP-18908 doesn't work. This is expected as that logic is only meant to be
> used for standard endpoints.
> If you are using a non-standard endpoint, check if a region is also provided,
> else fail fast.
> Also update documentation to explain to region and endpoint behaviour with
> SDK V2.
