Description of problem:

{
  "description": "FindResults failed on annotation template.openshift.io/expose-special.how: special is not found"
 }

Version-Release number of selected component (if applicable):
openshift v3.6.121
kubernetes v1.6.1+5115d708d7
etcd 3.2.0

How reproducible:
always

Steps to Reproduce:
1.Create a configmap template under test project like below:
"apiVersion": "v1",
                "kind": "ConfigMap",
                "metadata": {
                        "name": "special-config",
                        "annotations": {
                          "template.openshift.io/expose-how": "{.data['special.how']}",
                          "template.openshift.io/expose-type": "{.data['special.type']}"
                         }
                },
                "data": {
                        "special.how": "${DATA_1}",
                        "special.type": "${DATA_2}"
                }
        }],
2. Enable service broker to project test
3. Change namespace and cluster address in shared.shh
4. Change namespace to test in provision.sh and bind.ssh and execute these two scripts

Actual results:
{
  "description": "FindResults failed on annotation template.openshift.io/expose-special.how: special is not found"
 }

Expected results:
Should return output like below:
"credentials": {
   "special.how": "data1-SJ6",
   "special.type": "data2-K4E"
  }
