Allow use resource ID to specify public IP address in azure_loadbalancer
**What this PR does / why we need it**: Currently the Azure load balancer assumes that a Public IP address is in the same resource group as the cluster. This is not necessarily true in all environments, in addition to accepting a Public IP, we should allow an annotation to the `Service` object that indicates what resource group the IP is present in.

- leveraging Config struct (—cloud-config) to store backoff and rate limit on/off and performance configuration
- added add’l error logging
- enabled backoff for vm GET requests
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
