Storage S3Generic has missing field: Region

[kirillve]

Storage S3Generic has a missing UI field Region.

UI fields definition is here:
https://github.com/Requarks/wiki/blob/dev/server/modules/storage/s3generic/definition.yml#L13

And Region is not shown there as it's available at AWS S3:
https://github.com/Requarks/wiki/blob/dev/server/modules/storage/s3/definition.yml#L13

However, S3Generic processor supports Region: https://github.com/Requarks/wiki/blob/757398c2498f2883c4405d2d2ccf1c07b110d522/server/modules/storage/s3/common.js#L44

I suspect it should be a quick and easy fix.
