Directly support Azure Blob Storage instead of shimming to it via Minio

[mrzarquon]

Is your feature request related to a problem? Please describe

Currently we ship two versions of minio in our image list, because AKS blob storage was deprecated and we also want a way to support S3 for incluster storage, which pulls in another image.

This makes mirroring images and tagging them with release difficult because we can't easily flatten every image into a unique single tag for a release.

Describe the behaviour you'd like

A customer can use Azure Blob Storage directly.

Describe alternatives you've considered

Minio gateway was the alternative, but it's since been deprecated.

AFAIK, this will require a change in the content-service-api to add Azure as an option.

This will also require a change in the Installer's storage.go
