      Description

      Currently, for namenode-specific keys in HA, one must configure them as keyfoo.nameserviceid.namenodeid. However, in many cases all of the NNs in a nameservice would share the same value. So we should allow the configuration of "keyfoo.nameserviceid" to apply to all NNs. The resolution path for these keys would then be:
      keyfoo.nameserviceid.nnid
      keyfoo.nameserviceid (if above not set)
      keyfoo (if neither of above set)
