**Related command**
`az storage account update --resource-group resource-group --name storageaccount --custom-domain "www.example.com" --use-subdomain true`

**Describe the bug**
When running this command I expect that the return output is set to true from the JSON output.

This becomes more of an issue when trying to run subsequent update commands against the same storage bucket. For example trying to update the public access: `az storage account update --resource-group resource-group --name storageaccount --default-action Allow`

will give the following output:
```
(StorageDomainNameCouldNotVerify) The custom domain name could not be verified. CNAME mapping from www.example.com to any of , does not exist.
Code: StorageDomainNameCouldNotVerify
Message: The custom domain name could not be verified. CNAME mapping from www.example.com to any of , does not exist.
```

The CNAME update does work and the storage account can be accessed from the custom domain mapping however using any kind of AZ CLI updates afterward will fail with this configuration.

**To Reproduce**
1. Create Storage account
2. Configure for static web hosting
3. Configure with custom domain mapping using subdomain verification
4. Try running update command after custom domain mapping.

**Expected behavior**
I expect that the domain which is working correctly and verified via the portal would allow us to run commands in the Azure CLI.
