> Currently,  Non-windowed group aggregate is earlyFiring at count(1), that is every row
will emit a aggregate result. But some times user want config count number (`early firing
with count[N]`) , to reduce the downstream pressure. This JIRA. will enable the config of
e`earlyFiring` for  Non-windowed group aggregate.
