Set wsgi logger to use __name__

Although underneath this is the eventlet.wsgi.server server, Other
OpenStack projects, don't use that logger instead they use there own.

This will also mean the wsgi server will stop logging on just the
warning level.  We want wsgi server to at least log on info level
so it will log when a request is processed and what the return code is.

nvp:log only in rm router iface if port not found

The code currently raises when it's not able to find the port to be
deleted on the backend. This might happen, for instance, when the
port is manually removed or, in some cases, if port creation failed
in the first place.

There's little sense in raising when a resource to be removed is not
found; therefore this patch replaces the raise statement with a log
statement.
