      Add hidden configuration option "ipc.server.max.response.size" to change the default 1 MB, the maximum size when large IPC handler response buffer is reset.

      Description

      In HDFS-6460, the response buffers in o.a.h.ipc.Server.Handler was reset when the buffer grows beyond max size of 1MB. This frees heap from large responses occupying it. This max response size limit should be configurable. Details in subsequent comment.
