shill: DHCPClient: Output status metrics

Output metrics about the DHCP client status whenever this state
changes.  This will allow us track aggregate activity so we can
track the efficacy of the various DHCP client features.

BUG=chromium:384897
TEST=Unit tests + manual: restart shill and browse to chrome://histograms
