Deprecation warnings about pecan's _route and CORS

[Vladyslav Drok]

During unittests run, one can see the following issues:

/home/vdrok/work/ironic/.tox/py27/local/lib/python2.7/site-packages/pecan/__init__.py:122: RuntimeWarning: `static_root` is only used when `debug` is True, ignoring

ironic/api/app.py:89: DeprecationWarning: Method 'instancemethod.set_latent()' has moved to 'instancemethod.set_defaults()': CORS.set_latent has been deprecated in favor of oslo_middleware.cors.set_defaults

/home/vdrok/work/ironic/.tox/py27/local/lib/python2.7/site-packages/pecan/routing.py:242: DeprecationWarning: The function signature for ironic.api.controllers.root.RootController._route is changing in the next version of pecan.
     Please update to: `def _route(self, args, request)`.

    Fix usage of various deprecated methods

    Our unittest output complains about some of the codebase,
    described in more detail in the referred bug. This change
    fixes all of those places.

    static_root is now set only if debug=True is set in pecan
    configuration.

    Logging is now setup as part of the conf module import,
    so that unittests can use it.
