Conditionnaly wait for previous polling task

[vpaturet]

Summary

This is a follow-up PR for #6262 that improves the blocking wait logic: the polling thread is blocked only if the previous task takes longer than the polling interval.
In this case a log message indicates the additional waiting period.

The encapsulation of the task submission to the graph writer thread was missing in the SIRI-SX and SIRI-ET updater, this is fixed. As a result the callback saveResultOnGraph can be made private in PollingGraphUpdater.

The logic covers also the case when an updater sends several update tasks during one polling cycle.
