Blob storage service

[PhilipSkinner]

I'm pleased to announce that the blob storage service has been pushed out in the latest release.

The blob storage service allows you to upload files from:

• message queue handlers
• website/UI controllers
• api controllers

The documentation is not 100% complete for the blob service, what does exist can be found here:

• https://elementalsystem.org/src/support.documentation/services/blobService
• https://elementalsystem.org/src/support.documentation/blobStorage

The current system only supports filesystem storage - which is not great if you run elemental within a docker container as the files are stored within the container instance at the path /var/elemental/service.kernel/.sources/blobs - you can mount this as a volume to persist the files.

It is planned to add support for S3 compatible and azure blob storage backends.
