securityRules should support source address in plural

/kind feature

Describe the solution you'd like

As a User i want to group multiple network sources into one securityRule. At the moment i have to specify for each source one securityRule.

Anything else you would like to add:

In theory it should be an easy one to extend the securityRule struct by a new field called Sources and do the conversion to SourceAddressPrefixes in here.

But maybe it's also worth the discussion to keep the existing Source field and convert it directly to SourceAddressPrefixes as at least in theory, on Azure side nothing will (should) change.

Environment:

• cluster-api-provider-azure version: 1.9.0
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):

This is still on my radar.
