Changes nec-agent to catch RPC exceptions in the main daemon loop. It fixes the following two bugs. - nec-agent dies with RPC timeout in secgroup RPC (Closes-Bug: #1235106) - port_added message can be dropped when RPC timeout occurs (Closes-Bug: #1235111). Moves exception catch from PluginApi to the main daemon loop. Change-Id: I12394b739fc35bff271543f4625c5e3152e534ae
