Simplify profiling and benchmarks.
- Tweak the benchmarks to work with b.N where appropriate. In many cases,
b.N was simply being ignored. This creates an implicit dependency in the
user passing a reasonable benchtime (less than or equal to the actual
runtime of the test, or using the X syntax) otherwise the test runs
forever.
- In cases where the above is impossible, explicitly set benchtime from
the test wrapper, to prevent the above behavior (tensorflow).
- Drop the *Reverse variants, which are simply hey benchmarks. We should
just add a hey benchmark. The platforms benchmarks already include a
native platform, and thus these benchmarks are incredibly confusing.
(In other words, BenchmarkNginxReverse has nothing to do with an nginx
benchmark for runsc.)
- Remove the redunant Harness object, which contains no state, in order
to slightly simplify the code.
- Make Block and Heap profiling actually work, but setting appropriate
runtime parameters (and plumbing them through the config).
- Split the profiling into two phases: start and stop, since some will
need to be started early, and others will need to happen at the end.
