Fixed ID bug in China CDN experiment, added default, changed graphite metric name, and exposed CDN monitoring ENVs.

When configured, set an additional cookie with the CSRF
token for use by subdomains.

The cookie can have a different name than the default
CSRF cookie, preventing conflicts between cookies
from different domains (e.g. ".edx.org", "courses.edx.org",
and "edge.edx.org").

The new cookie is included only on the enrollment API
views so that the scope of this change is limited
to the end-points that require cross-domain POST requests.

Add pointer-events: none for fa-lock and fa-eye
