[chip-tool] Add flag to enable server interactions

Add "--server-interactions" flag to chip-tool which enables
server features, including advertising operational services.
This feature is needed to test persistent subscriptions
using chip-tool, which requires that chip-tool be
discoverable after the publisher node reboots.
