Should provide better error reporting when there is no 'benchmark.json' file in a benchmark.

[elavoie]

The only issue I’ve had with Wu-Wei is when setting up the benchmark in the first place; the documentation doesn’t mention that a benchmark.json is strictly required, and Wu-Wei won’t fail with a related error. If this file is missing, it seems, from a user’s perspective, that one is automatically generated with a missing mandatory field (version), raising a generic JSON validation error. This is especially annoying since there is no mention of which fields are required and the documentation does not mention version for benchmarks at all.
