Add perflock to funcbench

[bwplotka]

This ensures better safety in terms of CPU results - useful for shared environments.

Would be nice to do it programmatically: aclements/perflock#6

Yes this would be super nice I think! Let's see what aclements has to say.

Also, I am just unsure about how this would behave in containerized environments. Currently funcbench runs on a k8s pod in the main k8s node itself. Any suggestions?

I think it was tried running directly on a GCP VM but the results were more or less the same.
@krasi-georgiev @nevill would have more info on this.

Well the thing is that this is literally global locking mechanism allowing to run more than one benchmark at the time (:
Useful when w have one VM!

I am not sure how it works in a containerized environment though (:

[krasi-georgiev]

Yes lets try it!

[bwplotka]

funcbench was removed from the project, for now.
