Subject: lldp: T7165: add support to enable only rx or tx on specific
interface
LLDP is a stateless protocol which does not necessitate sending to receive
advertisements. There are multiple scenarios such as provider peering links in
which it is advantageous to receive LLDP but not disclose internal information
to the provider.
Add new CLI command:
* set service lldp interface <name> mode [disable|rx-tx|rx|tx]
The default is unchanged and will be rx-tx.
Furthermore if an interface has an explicit LLDP disable configured under
"set service lldp interface <name> disable" this will be migrated to
"set service lldp interface <name> mode disable"
