Azure: Create blob container if not found.

[appkins]

What this PR does / why we need it:
This PR aligns with the fallback behavior in Thanos object store for creating azure blob containers when they do not exist. Loki depends on the containers to function and already configures the necessary credentials for creating a container. It follows that Loki should create any required containers to prevent running in a failed state.

This behavior matches the code for Thanos here:
https://github.com/thanos-io/objstore/blob/main/providers/azure/azure.go#L167

ctx := context.Background()
	_, err = containerClient.GetProperties(ctx, &container.GetPropertiesOptions{})
	if err != nil {
		if !bloberror.HasCode(err, bloberror.ContainerNotFound) {
			return nil, err
		}
		_, err := containerClient.Create(ctx, nil)
		if err != nil {
			return nil, errors.Wrapf(err, "error creating Azure blob container: %s", conf.ContainerName)
		}
		level.Info(logger).Log("msg", "Azure blob container successfully created", "address", conf.ContainerName)
	}

I tried to match the behavior as closely as possible while using the existing azblob implementation in Loki (vs the azure sdk library in Thanos object store).
