dpif-netdev: Add command to get dpif implementations.
This commit adds a new command to retrieve the list of available
DPIF implementations. This can be used by to check what implementations
of the DPIF are available in any given OVS binary. It also returns which
implementations are in use by the OVS PMD threads.
Usage:
$ ovs-appctl dpif-netdev/dpif-impl-get
