feat: support viploadbalancer controller

[wangxye]

What type of PR is this?

/kind feature

What this PR does / why we need it:

As the second-level controller for the multi-region load balancer, It is used to support the control of high availability of virtual IP based edge services, monitor poolservice changes, and is used to synchronize vrid changes to the vip agent at the edge.

Special notes for your reviewer:

Does this PR introduce a user-facing change?

Support left-closed-right-open ip assignment：

# if you use vip for load-balancer, you should annotate the vip address for the nodepool.
kubectl annotate nodepool hangzhou openyurt.io/address-pools="192.168.0.1-192.168.1.0, 10.0.1.0"

# For vip-type load balance, if you want to specify a vip for a service, you needs to annotate the specified address.
kubectl annotate service nginx service.openyurt.io/vip="192.168.0.1-168.0.3, 10.0.1.0"

I have updated the logic of syncPoolService to first synchronize the validly allocated vrids in the cluster first, which is used to support the user-specified mode of vrid deployment. In addition, we will perform unified allocation for unallocated or vrid exceptions, which include cases where the annotation of the vrid is null, the vrid is abnormal, and the vrid is out of range. This layer of logic will also be judged in reconcileDelete.
