Add support for keepalive functionality to DPDK datapath. By default,
the keepalive is OFF and can be enabled/disabled either at start time.
For eg:
To enable keepalive feature.
'ovs-vsctl --no-wait set Open_vSwitch . other_config:keepalive=true'
To set timer interval of 50ms for monitoring packet processing cores;
'ovs-vsctl --no-wait set Open_vSwitch . \
other_config:keepalive-interval="50"
To set shared memory block name where the events shall be updated
'ovs-vsctl --no-wait set Open_vSwitch .
other_config:keepalive-shm-name="/dpdk_keepalive_shm_name"'
