papi: prevent message_table inconsistencies

Socket transport is maintaining message_table to map
message name to index. After disconnect and re-connect,
the VPP may have been restarted with different set of plugins,
so message_table has to be wiped.

+ Edited MAINTAINERS to recognize "papi" as a separate component.
