This series cleans up the generation and value types used in gms / gossiper.
Currently we use a blend of int, int32_t, and int64_t around messaging.
This change defines gms::generation_type and gms::version_type as int32_t
and add check in non-release modes that the respective int64 value passed over messaging do not overflow 32 bits.
Closes#12966
