Satori/NamingUnnamedThings

We're looking for a name to name the _things_ that do discovery.

We'd like to have the name be:
 * unique and identifiable to satori so as not to be confused with other generic or openstack-used terms
 * socially likable (ex. inquisitor or assessor don't pass!)
 * descriptive: talks to what these things do - collect data
 * applies to both control and data plane

Proposed:
 * agents
 * analysts
 * assessors
 * collectors
 * feelers
 * gatherers
 * inquisitors
 * plugins
 * probes
 * providers
 * sensors


 * PLEASE ADD SUGGESTIONS *
