Graphite values ULL suffix

[RyazMax]

Using graphite 1.1.7 (docker image graphiteapp/graphite-statsd) faced with graphite ignoring some default metrics from module because of ULL suffix of values.

Log sample:

dockerd-current[19642]: 09/07/2020 10:46:34 :: [listener] invalid line received from 172.17.0.1, ignoring [myapp.tnt_space_total_bsize;name=transfers;engine=memtx 11511360ULL 1594291594]

The same behavior noticed with metrics: tnt_space_bsize, tnt_cfg_current_time
