allow resize tests to run

resize tests were turned off explicitly, which they shouldn't be
turn these back on in a default config as we've set nova to allow
resize_to_same_host.

Move auth_token configurations to quantum.conf

keystone auth_token middleware now allows quantum to have auth_token
configuration in quantum.conf. auth_token middleware supports
auth_token configuration both in api-paste.ini and quantum.conf,
so we can apply this change at any timing.

Add option to make screen starting more robust.

We have seen a number of failures in ci where a host is overloaded
and the 1.5 second sleep before stuffing data into screen is not
long enough. This means the service doesn't start and tests fail.

This change adds a config option to allow us to turn off the developer
friendly option to stuff text into the screen. When SCREEN_DEV is
set to False it will use a simple exec in screen instead of stuff.
This should be far more reliable because we don't have to wait
for bash to start.
