chore(ci_visibility): add support for pytest_bdd to v2 plugin

[romainkomorndatadog]

This adds support for the pytest-bdd plugin to the new version of the pytest plugin, bypassing the ddtrace.pytest_bdd plugin and instantiating a "subplugin" on demand when pytest-bdd is detected and ddtrace is enabled.

To support the way the legacy pytest-bdd plugin worked, new functionality is added:

• InternalTestSession.get_tracer() to have access to the tracer used by Test Visibility
• InternalTest.overwrite_attributes() to allow overwriting attributes that have already been set (or in the case of the suite name, that are automatically set based on test hierarchy)
