DeltaLatency events are not frequent enough in automation

[vladsud]

union office_fluid_ffautomation_*
| where Event_Time > ago(14d)
| where Data_eventName contains "DeltaLatency"
| summarize count(), toint(avg(Data_duration)), toint(percentile(Data_duration, 95)) by Data_driverType

This gives me 499 hits, only for FRS.
We need to adjust how often we collect it to make sure automation collects enough data to be useful.
Example of investigation where it would be super useful - #8908

At the same time we should be careful not to submit too much data in production.
Likely it's a problem of when we collect it, i.e. something like count % 1000 === 0 to be changed to count % 1000 === 1 to ensure every connection records one data point (that's pure guess)
