Bug 8476 Add support for logical switch replication mode

With OVS 2.6, the Logical Switch table, in the hardware_vtep schema, has
a new field, replication_mode. This bug will be used to add support to
netvirt, ovsdb, and genius for setting the replication_mode of logical
switches. The default will be for ODL to set the replication_mode
to "source_node" when creating logical switches.

Refer to [1] for more details on replication_mode.

This patch depends on ovsdb patch:
