Open-vsx deployment update issues.

While working through the deployment update this morning it was commented that we would need to make some changes to our ehcache deployment[1].

AFAIA we are not currently deploying ehcache, so how do we deploy an update to open-vsx that doesn't require providing/deploying any extra services?
