Use agent protocol for Benchmarks

[jakubno]

Background

Using Agent protocol to run benchmarks. I added downloading and uploading files, this allows to benchmark agents remotely and overall it simplifies the setup.

Other insights are more than welcomed!

Changes

Add option to run benchmarks in API mode, no need to change your agent, if you use agent protocol.
