The user-provided edge subnets (BYO VPC), created on zone type local-zone, is not tagged with kubernetes cluster tag `kubernetes.io/cluster/<infraID>` and value `shared` in install time.

Subnets in regular/default zones are correctly tagged.

The edge subnets created by installer in IPI is also tagged with value `owner`, so we need to check if there is an issue BYO VPC scenario or the implementation was just not replicated to edge subnets.

    4.19 (or since edge subnets, 4.14+?)

    always

    1. create vpc
    2. create subnet in local zone
    3. create install-config with regular zones, and edge zones
    4. create the cluster
    5. check the tags of subnets in local-zones
