neutronclient works with keystone v3 API. The document hasn't been updated yet.
Document update patch is under review https://review.openstack.org/#/c/330722/.
It may help you.

> I wonder how horizon is able to “set conext” to a domain and then operations are valid with context.

Horizon caches token information in its session store.
It is similar to keystoneauth Session object but it is a bit different

> Perhaps one need to just learn the API and program from there without any libraries or CLI wrappers.

While it depends on your need, generally reusing existing python
bindings will help you.
