Add Session.name

[drhagen]

Being able to know what session you are in is useful for a variety of reasons. One of which is to be able to name artifacts in a way that is traceable back to the session, such as with code coverage reports. Right now, the only solution is to dig down to session._runner.friendly_name:

import nox


@nox.session(python=['3.6', '3.7', '3.8', '3.9'])
def test(session):
    session.install('.')
    session.install('pytest', 'pytest-cov')
    session.env['COVERAGE_FILE'] = f'.coverage.{session._runner.friendly_name}'
    session.run('python', '-m', 'pytest', '--cov', 'tests/')

This PR exposes that private attribute via a public property:

import nox


@nox.session(python=['3.6', '3.7', '3.8', '3.9'])
def test(session):
    session.install('.')
    session.install('pytest', 'pytest-cov')
    session.env['COVERAGE_FILE'] = f'.coverage.{session.name}'
    session.run('python', '-m', 'pytest', '--cov', 'tests/')
