Fixes #27254
Relate PR: #27256

This PR will add the subscription ID and resource group to the service so we know where the storage account located, also works for cross subscription. For the existing resource managed by AzureRM the subscription ID and resource group are null, AzureRM cannot find the storage account if it's not in the same sub as MLW, this PR will fix this.

Thanks for this @xuzhang3 - I have just left one comment to note that we currently have an env var for an alternative subscription id. Could we update the tests to use this instead and re-run them and then we can take another look at this? Thanks!

[catriona-m]

Could we remove this and use ARM_SUBSCRIPTION_ID_ALT instead for an alternative subscription id?

@catriona-m test case updated.
