(feature) Azure BlobStorage exporter

[thomaspoignant]

Requirements

In order to continue GO Feature Flag support to major cloud provider we want to bring the same support as GCP and AWS for Azure.

To do this, we want to let GO Feature Flag users the possibility to export their flag usage to Azure BlobStorage.
For this, we want to have a Azure Blob Storage exporter that will store all the exported data directly to Azure.

Things to take in consideration:

• We can use the azure SDK to be able to communicate with BlobStorage (https://github.com/Azure/azure-sdk-for-go/tree/main/sdk/storage/azblob)
• We should be able to give the credentials through the normal mechanism of authentifcation of the GO sdk.
• This should work both as GO module and in the relay-proxy.

This exporter will be very similar to the S3 exporter and Google Storage exporter.

Hi @thomaspoignant would you prefer auth via azblob or via azidentity or you wouldn't mind having both as an option?
