[trec-kba] fields in submission json object

[John R. Frank]

KBAers,

In the JSON string at the top of the submission file, some of the
fields may be unfamiliar:

  poc_email -- Point of Contact: email address of a person who can answer
questions about your system

poc_name -- name of that person.


team_name -- the full name of your organization, which most teams
shorten when constructing the team_id string.
