[PATCH RFC 34/59] controller: Make a useful config file

[Ronald Rojas <ronladred@gmail.com>]

From: George Dunlap <george.dunlap@citrix.com>

Allow a simple "skeleton" config file which can be adapted for the
particular use case.  Have 'plan' expand this with the real benchmark
plan.

Include "sample.bench" as a template to modify.  Also update the
README.md accordingly.
