As part SERVER-14364 and SERVER-7918, BSON values from serverStatus were changed from 32-bit to 64-bit. The SNMP MIB was never updated to reflect this change in data type because to make the change would be considered a breaking change. A quick hack to truncate these 64-bit counters as 32-bit counters was done as part of SERVER-48567.

Since changing the type of a field per RFC2578 Section 10 requires changing the OID, this an involved amount of work that requires us to deprecate the existing OID, add a new value, and then potentially remove the old one in a future LTS release.

We should decide if and when we want to do this work.
