1. eni: Fix unexpected IP release when agent restarts …

   When cilium agent in eni mode restarts, ciliumnode custom resource
   is cleared and refilled by several updates. Specifically,
   Status.IPAM.Used map which holds all used IPs is first updated
   to an empty map before endpoints finish restoration.
   
   This becomes critical if `--aws-release-excess-ips` is enabled
   since cilium operator treats empty IPAM.Used map as no address used
   hence releases addresses arbitraryly, causing restored endpoints
   disconnected.
   
   This patch fixes this by combining per endpoint update requests
   into one update request after all endpoint restoration finishes so
   that Status.IPAM.Used keeps the desired state during agent restart.
