AzureVpcPeering VnetAddressSpacesOverlap

[vandjelk]

Description

When local and remote networks subnets have overlapping CIDRs reconciler fails to create VPC peering and writes cloud provider API error into status condition exposing sufficient information to the user.

Instead of writing API error to the status condition Cloud Manager should handle the error and write meaningful message to the user something like:

Cannot create or update peering. Virtual networks cannot be peered because their address spaces overlap. Overlapping address prefixes: 10.0.0.0/24
