[swss] Add support for gearbox phys (#1321)

Add support for gearbox phys based on sonic-sairedis support of multiple switches * builds on support for multiple switches in sonic-sairedis * adds gearsync daemon * parsers for gearbox-related configuration files, plus unit tests * gearboxutils for determining if gearbox supported and other functions * changes to portsorch and orchagent to support gearbox creation and attributes
