This is the extension of https://github.com/ooni/probe-cli/pull/431, and my final deliverable for GSoC 2021. The diff introduces: 1) The new `testhelper` which supports testing multiple IP endpoints per domain and introduces HTTP/3 control measurements. The specification of the `testhelper` can be found at https://github.com/ooni/spec/pull/219. The `testhelper` algorithm consists of three main steps: * `InitialChecks` verifies that the input URL can be parsed, has an expected scheme, and contains a valid domain name. * `Explore` enumerates all the URLs that it discovers by redirection from the original URL, or by detecting h3 support at the target host. * `Generate` performs a step-by-step measurement of each discovered URL. 2) A prototype of the corresponding new experiment `websteps` which uses the control measurement of the `testhelper` to know which URLs to measure, and what to expect. The prototype does not yet have: * unit and integration tests, * an analysis tool to compare the control and the probe measurement. This PR is my final deliverable as it is the outcome of the trials, considerations and efforts of my GSoC weeks at OONI. It fully integrates HTTP/3 (QUIC) support which has been only used in the `urlgetter` experiment until now.

Directory github.com/ooni/probe-engine/experiment
This directory contains the implementation of all the supported experiments, one for each directory. The OONI spec repository contains a description of all the specified experiments.
Note that in the OONI spec repository experiments are called nettests. Originally, they were also called nettests here but that created confusion with nettests in ooni/probe-cli. Therefore, we now use the term experiment to indicate the implementation and the term nettest to indicate the user facing view of such implementation.
Note that some experiments implemented here are not part of
the OONI specification. For example, the urlgetter
experiment is not in the OONI spec repository. The reason why
this happens is that urlgetter is an experiment "library" that
other experiments use to implement their functionality.
Likewise, the example experiment is a minimal experiment that does nothing and you could use to bootstrap the implementation of a new experiment. Of course, this experiment is not part of the OONI specification.
