* [voq/systemlag] VOQ System lag functionality

Signed-off-by: vedganes <vedavinayagam.ganesan@nokia.com>

Changes for voq system lag implementation
(1) Portsorch changes for allocating unique lag id from chassis ap pdb
and sending the id in system port aggregator id attribute while creating
lag local LAG
(2) Portsorch changes to synd local LAG and local LAG members to
chassis app db. The sync-ing includes the allocated unique system lag id
(3) Portsorch changes to process remote system lag from chassis app db
and create lag entry in local asic db with received system lag id
(4) Interface orch changes to identify local or remote interfaces
(for both port and lag)
(5) Orchdaemon changes in orchagent intialization to get hostname and
asic_name attributes from DEVICE_METATDATA. These are used for unique
system lag name derivation
