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.
**Which issue this PR fixes**: fixes#53274#52129
**Special notes for your reviewer**: *first time golang user, please forgive the amateurness*

Added service annotation to set Azure DNS label for public IP
**What this PR does / why we need it**: Added a feature to set the DNS label for public IPs in the Azure cloud.
For example:
```
apiVersion: v1
kind: Service
metadata:
annotations:
service.alpha.kubernetes.io/label-name: myservice
...
```
Will resolve myservice.westus.cloudapp.azure.com to the service's IP.
**Which issue this PR fixes**: fixes#44775
**Special notes for your reviewer**: Note that this is defining a new annotation, so feel free to point out if there is a preferred convention or anything else that needs to be done.
**Release note**:
```release-note
New service annotation "service.beta.kubernetes.io/azure-dns-label-name" to set Azure DNS label name for public IP
```

Add extra logging to azure API get calls
**What this PR does / why we need it**:
This PR adds extra logging for external calls to the Azure API, specifically get calls.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #
This will help troubleshoot problems arising from the usage of this cloudprovider. For example, it looks like #43516 is caused by a call to the cloudprovider taking too much time.
EnsureHostInPool() submits a GET to azure API for VM info. We’re seeing this on agent node kubelets and would like to enable configurable backoff engagement for 4xx responses to be able to slow down the rate of reconciliation, when appropriate.

Add E2E tests for Azure internal loadbalancer support, fix an issue for public IP resource deletion.
**What this PR does / why we need it**:
- Add E2E tests for Azure internal loadbalancer support: https://github.com/kubernetes/kubernetes/pull/43510
- Fix an issue that public IP resource not get deleted when switching from external loadbalancer to internal static loadbalancer.
**Special notes for your reviewer**:
1. Add new Azure resource tag to Public IP resources to indicate kubernetes managed resources.
Currently we determine whether the public IP resource should be deleted by looking at LoadBalancerIp property on spec. In the scenario 'Switching from external loadbalancer to internal loadbalancer with static IP', that value might have been updated for internal loadbalancer. So here we're to add an explicit tag for kubernetes managed resources.
2. Merge cleanupPublicIP logic into cleanupLoadBalancer
**Release note**:
NONE
