 As result of #930 we found at least two possible issues about names in MIB
 of stats-snmp in the current design as described in the prototype
 implement in the experiment branch(kambe-SNMP-stats) and in the document
 StatsModule#StatsSnmp(#1448).

 * The MIB of stats-snmp is statically generated when the BIND 10 is made.
 And if we change the daemons to run, for example, when we disable the Auth
 daemon and enable the Resolver daemon, there may be an inconsistency
 between such static MIB and the statistics list which is dynamically
 answered by the Stats daemon.

 * There might be name duplication in MIB. For example, if one name
 authQueriestcp is defined in MIB as two different OIDs
 .1.3.6.1.4.1.2021.255.0.0 and .1.3.6.1.4.1.2021.255.0.2.0.2, we can
 access to the object firstly matched in MIB by authQueriestcp but we
 cannot access secondly matched one by same way.

 Improve current data mapping between specfile and MIB to resolve these
 design issues, and then revise the document StatsModule#StatsSnmp.
