mw_jwt benchmarks added, existing benchmarks fixed (TykTechnologies#1509

)

added more benchmarking instrumentation

- started with `mw_jwt`
- added `utils/ci-benchmark.sh` which just runs benchmarking and has optional parameter - regex for benchmarks to run
- travis will run it but it will just produce numbers - no performance/memory allocation asserts there
