lacp: passive mode support [VPP-1551]

By definition, passive mode means the node does not start sending lacp pdu until
it first hears from the partner or remote.

- Rename ptx machine's BEGIN state to NO_PERIODIC state.
- Put periodic machine in NO_PERIDOIC state when the interface is enabled for
lacp. ptx machine will transition out of NO_PERIODIC state when the local node
hears from the remote or when the local node is configured for active mode.
- Also add send and receive statistics for debugging.

lacp: partner may time us out if fast-rate is configured [VPP-1247]

We should be sending LACP PDU every second if the partner has LACP_TIMEOUT flag
set which means it will time us out in 3 seconds.

Add interface name for lacp trace

lacp: faster convergence for slow-rate config option

Do fast-rate if we are not yet synchronized with the partner.

Stop sending LACP updates as a flash in the worker thread. Just expire the
timer and let the lacp_process handle sending LACP PDU.

bond: Add bonding driver and LACP protocol

Add bonding driver to support creation of bond interface which composes of
multiple slave interfaces. The slave interfaces could be physical interfaces,
or just any virtual interfaces. For example, memif interfaces.

The syntax to create a bond interface is
create bond mode <lacp | xor | acitve-backup | broadcast | round-robin>

To enslave an interface to the bond interface,
enslave interface TenGigabitEthernet6/0/0 to BondEthernet0

Please see src/plugins/lacp/lacp_doc.md for more examples and additional
options.

LACP is a control plane protocol which manages and monitors the status of
the slave interfaces. The protocol is part of 802.3ad standard. This patch
implements LACPv1. LACPv2 is not supported.
To enable LACP on the bond interface, specify "mode lacp" when the bond
interface is created. The syntax to enslave a slave interface is the same as
other bonding modes.
