AGL Test Framework writing tests: Fix tree and re-write
Fixes SPEC-2314 I changed the file prefix to "afg-agl" from "afg" for the file "aft-agl-middlename.json". Allows the configuration file to be found. I also cleaned up the English in the section for grammar and readability. Change-Id: Ie2a5ff1d17928385dae885d5f3fb1b962de2283b Signed-off-by: Scott Rifenbark <srifenbark@gmail.com>

-- `info` (optional): self-explanatory
-- `api`: the name that your test binding will take. Used to be the test api's
