Benchmark flow

[nuts-rice]

Addresses #909 by:

1. adding a bash script for running cargo bench and moving the benchmark reports to a directory accessible from root of the repo
2. adding barebones benchmarks for http_tracker_core + udp_tracker_core

the mv lines in the bash script are using the -b option as i'm not sure how comparing target with PR branches should be handled.

Hi @nuts-rice I have superseded this PR by #1371.

I have only fixed compilation and linting errors and other minor changes.

I think it's a good starting point but I have some questions:

1. How we can extract the data from reports in a workflow to compare results.

My idea was to run it and get a number of announce requests per second with the base branch version and the new branch in the PR. And make the workflow fail if the difference was over a threshold (maybe 5%).

2. I don't know why you only test connect requests in the UDP tracker.

I would also check announce requests. I guess the problem is you have to connect before announcing. If we don't want to re-connect every X announce requests we can increase the cookie lifetime. The default value is 2 minutes.

Thank you very much for your contribution!
