create a common endpoint/configmap object lock based HA code block that can be reused by each control plane component #99

Research has been done and each component resource lock will use namespace + kind as its uid for its lock record. |
|
will write a draft for discussion. |

It is not urgent after discussion. Therefore it has been move to Spring release. For kube-controller-manager and kube-scheduler, both of them use resource lock mechanisms. |

What would you like to be added:
A common code block that can be shared by all global scheduling platform control plane components to support HA.
Why is this needed:
Each control plane component needs to support HA. We can leverage existing k8s endpoint/configmap object based lock mechanism to add HA to each control plane component. Since they share quite some common code pieces, we can extract these code pieces and put them into a common code block so that every component can reuse this code block to implement its HA.
