Run bench with k6 and all runtimes

[joanhey]

Now we only need to output the data to create a table and graph.
It makes sense to automate it.

make run/bench/all
make run/bench/all vus=1000
make run/bench/all vus=10000 duration=10s
// default vus=100 duration=30s


//only 1 runtime
make run/bench runtime=007-frankenphp
make run/bench runtime=007-frankenphp vus=1000
make run/bench runtime=007-frankenphp vus=10000 duration=10s

TIP:
In another terminal run:
docker stats

To have realtime metrics from the containers running the bench.
