What this PR does / why we need it:

A mutating webhook is introduced in yurt-manager component for adding NodeAffinity to pods with annotation["apps.openyurt.io/exclude-host-network-pool"] = true. The NodeAffinity indicates that the pods don't want to be scheduled to nodes in hostNetwork mode NodePool.

Users should add annotation ["apps.openyurt.io/exclude-host-network-pool"] = true manually to pods if they don't want to run pods on edge nodes in hostNetwork mode nodepool.

Which issue(s) this PR fixes:

Fixes #1935
