introduce an experimental approach for allowing dynamic addition of hooks from plugin. Plugins may register new hooks by implementing the new

pytest_registerhooks(pluginmanager)

and call

    pluginmanager.registerhooks(module)

with the referenced 'module' object containing the hooks.

The new pytest_registerhooks is called after pytest_addoption
and before pytest_configure.
