Subject: Fix #4339 - Save a last run report summary to
 $statedir/last_run_summary.yaml

Once a configuration run is done, puppetd will save on the node a
yaml summary report roughly akin to:

---
  time:
    notify: 0.001025
    last_run: 1289561427
    schedule: 0.00071
    config_retrieval: 0.039518
    filebucket: 0.000126
  resources:
    changed: 1
    total: 8
    out_of_sync: 1
  events:
    total: 1
    success: 1
  changes:
    total: 1

This is almost an hash version of the current --summarize output, with
the notable exception that the time section includes the last run unix
timestamp.

The whole idea is to be able to monitor locally if a puppetd does its job.
For instance this could be used in a nagios check or to send an SNMP trap.
The last_run information might help detect staleness, and this summary
can also be used for performance monitoring (ie time section).
The resource section can also show the number of failed resources.
