Is your feature request related to a problem? Please describe.

Right now, the countconnector uses time.Now() for the timestamp of the metric.

Describe the solution you'd like

The metric generated from a count should be using the start timestamp of the first record ingested, and the timestamp of the latest record ingested.

Describe alternatives you've considered

Hi @atoulme, are you saying to make the default timestamp the first timestamp of the batch and add another end_timestamp (or something along those lines) attribute?

[akats7]

Ah nevermind, I see what you're saying, didn't see the StartTimestamp on the datapoint types. Makes sense, I can contribute this.

I wonder if this should be configurable? I could imagine users depending on the current behaviour to count the number of spans/logs/whatever, relative to the collector's time rather than the producers of data.
