openshift-ansible: Origin Centos for release 3.11 binaries are not available

Description

Origin Centos for release 3.11 binaries are not available.

If I checkout the release-3.11 branch, and run the prerequesites ansible recipe, it fails to find origin-excluder for the 3.11 release.

Only up to 3.10 are available:

http://mirror.centos.org/centos/7/paas/x86_64/openshift-origin/

For example, for the origin-excluder package, it stops at 3.10:
