Make sure BreakdownMetricsProvider prints 1K warning only once per collection

[gregkalapos]

Solves #1361

Prior to this PR once BreakdownMetricsProvider reached the 1K metricset limit, it pinted a warning after each transaction. With a high number of transactions this can span logs.

This PR changes this to print this log only once in every metics collection round. So in every MeticInterval (by default 30sec) we'll print the warning once if the 1K limit is reached. This also reflects reality better, since once the 1K limit is reached, we reset it after the current List<MetricSet> is sent to the server.

Any chance that this fix will be released soon? It really creates noise in the logs
