This constitutes a large change in how we will parse different data
formats going forward (for the plugins that support it)
This is working off @henrypfhu's changes.
This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.
closes#564
Reuses same logic as the plugins for filtering points, should be only
a marginal performance decrease to check all the points before writing
to the output.
Added examples to the README as well (for generic pass/drop as well as
output pass/drop/tagpass/tagdrop).
