Wrong HOST when calling blob.get_signed_url in local api_root

[erincar]

gcloud-aio/storage/gcloud/aio/storage/blob.py

Line 34 in e738eb8

HOST = 'storage.googleapis.com'

Hello,

I am running fake-gcs-server in my local compose stack and connect to it via gcloud.aio.storage.Storage.
I set up the api_root via STORAGE_EMULATOR_HOST, and can see that the correct one is used.

However, when generating a signed URL for a blob, I receive one starting with storage.googleapis.com.
I am suspecting that is due to the hardcoded HOST referred above.

Is this usage intended? Or should the HOST be pointing to the api_root instead?
