osd: distinguish between osd_pg_stat_report_max_(epoch|seconds)

osd: distinguish between osd_pg_stat_report_max_(epoch|seconds)

osd_pg_stat_report_max was previously used as either a max time in seconds
or a max number of epochs.  Instead, separate into two configs and adjust
PeeringState::prepare_stats_for_publish to check both.

Additionally, this commit removes a superfluous check in
PeeringState::Active::react(const AdvMap&) and calls publish_stats_to_osd
unconditionally as with other callers in PeeringState.
