This commit adds support to query keepalive statistics. Datapath health
status can be retrieved as follows:
$ ovs-appctl keepalive/pmd-health-show
Keepalive status
keepalive status : Enabled
keepalive interval: 1000 ms
PMD threads : 8
PMD CORE STATE LAST SEEN TIMESTAMP
pmd62 0 ALIVE 8632183482028293
pmd63 1 ALIVE 8632183482028425
pmd64 2 ALIVE 8632190191004294
pmd65 3 ALIVE 8632183482028525
pmd66 4 GONE 8612183482028117
pmd67 5 ALIVE 8632190191004984
pmd68 6 ALIVE 8632190191005713
pmd69 7 ALIVE 8632190191006555
