What this PR does / why we need it:

Azure cloud provider has a limited support for service tags by annotations:

kubernetes/staging/src/k8s.io/legacy-cloud-providers/azure/azure_loadbalancer.go

Lines 96 to 97 in 32b37f5

	supportedServiceTags = sets.NewString("VirtualNetwork", "VIRTUAL_NETWORK", "AzureLoadBalancer", "AZURE_LOADBALANCER",
	"Internet", "INTERNET", "AzureTrafficManager", "Storage", "Sql")

But according to https://docs.microsoft.com/en-us/azure/virtual-network/security-overview#service-tags, there are actually much more service tags than this list. Hence, errors would happen if the service tag is not included in the above list.

This PR fixes the issue by removing the static list from the cloud provider and let Azure API validate whether the service tag is supported or not. If illegal service tags are provided, error events would be sent for the service.

Which issue(s) this PR fixes:

Fixes #77717
