Setting ceph['enabled'] = false in glance/values.yaml has no effect

[dulek]

Kubernetes Version (output of kubectl version):
1.5.3

Helm Client and Tiller Versions (output of helm version):
2.2.3

Development or Deployment Environment?:
Development

Release Tag or Master:
master

Expected Behavior:
setting ceph.enabled = false should remove rbd from glance-api.conf

What Actually Happened:
It's still configured there, so without Ceph image upload will fail with 500.

How to Reproduce the Issue (as minimally as possible):
Just set the option, deploy and try to upload the image.

Any Additional Comments:
This option is not used in _glance-api.conf.tpl, should it simply get removed?
