Puppet agents reporting should handle duplicates well.

tl;dr - We can skip puppet reports duplicates thus lowering for about ~ 10 times number of cichange records. 
I observed, that number of puppet agents send puppet reports for the same configuration version and host. (in the interval of 30 mins)

Further, i did some research for big data:
```
 mysql> select count(*),sum(x) from (select count(configuration_version) as x from cmdb_cichangepuppet where   host='t10720.te2' group by configuration_version having count(*)>1) temp; 
 +----------+--------+
 | count(*) | sum(x) | 
 +----------+--------+
 |       57 |   3702 |
 +----------+--------+
 1 row in set (2.13 sec)

 mysql> select sum(x) from (select count(configuration_version) as x from cmdb_cichangepuppet where  host='t10720.te2' group by configuration_version having count(*)=1) temp;
 +--------+
 | sum(x) |
 +--------+
 |    145 |
 +--------+
 1 row in set (2.15 sec)
```
As observed, instead of  3847 records, we can lower this number to 202 - reducing 20x times - by storing only unique(configuration-version,host) records.
