   * here instead of RPC layer because at the time of opening/authenticating
   * the connection it doesn't know what all RPC calls user will make on it.
   * Also new NMToken is issued only at startContainer (once it gets
   * renewed).
   *
   * 2) It should validate containerToken. Need to check below things. a) It
   * is signed by correct master key (part of retrieve password). b) It
   * belongs to correct Node Manager (part of retrieve password). c) It has
   * correct RMIdentifier. d) It is not expired.
