Add functional tests for devstack gate

This patch adds 'functional' tests that will be run by DSVM gate.
A 'cloudsConfig.js' file reads 'clouds.yaml' and converts it to json.
'clouds.yaml' file is searched from the following locations:
 - current directory
 - ~/.config/openstack
 - /etc/openstack
The first file found wins.

For browser, webpack uses a 'yaml' loader and rewrites
'helper/cloudsConfig.js' requirement to 'json!yaml!clouds.yaml'.

A dummy test has been added to demonstrate use of devstack config.
