fetch_teams

[yarikoptic]

to be more specific than fetch_members. Example is actually our con organization: we have teams for internationalization etc, overall too many members and too non-specific to include all. But if we specify some team(s), I think it would be fine.

Instead of adding another option, I guess could be made into fetch_members would take any list as a list of teams... but becomes too cryptic -- bool/regex/[teams]

edit: might want to allow teams: object with "include" or "exclude" regexes , having which would reply in general true to fetch members but then filter out one way or another based on teams.
