Pass delete options in proxy store

[gitlawr]

Address issue: rancher/rancher#17823

Problem:
There is no way to pass gracePeriodSeconds for force deletion

Solution:
Get deletion options in query params and pass it in proxy store

More Infos:

1. In this solution, The APIs do force deletion by passing gracePeriodSeconds=0, which is the same way as apiserver.
2. Kubernetes apiserver accepts delete options from entity-body of DELETE requests before v1.4, and support both query params and entity-body since v1.4. Because the usage of request body in DELETE request is kinda discouraged in HTTP/1.1 semantics and not supported by some clients. However, kubectl still pass deletion options to apiserver using request body. Refer to this issue for details.
3. This pr reuses ParameterCodec utilities which is how apiserver processes the deletion options, see
