Save the unsent log info for metrics
- Add the optional dedicated preference for the unsent log info.
- Save the unsent log info at each time the unsent log persisted.
- Read the unsent log info at next browser startup.
- Define the record method in UnsentLogStoreMetrics to record
the count of the unsent samples, the count of the sent samples
the percentage of unsent samples and the persisted logs size.
