Description of problem:
When we add values from secrets as a volume and define specific keys & paths, keys and paths are not shown in volume info

Version-Release number of selected component (if applicable):
v1.5.0-alpha.0+33a69c5-73

How reproducible:
Always

Steps to Reproduce:
1.Create secret
$ cat >> mysecret.yaml << EOF
apiVersion: v1
kind: Secret
metadata:
  name: mysecret
type: Opaque
data:
  password: MWYyZDFlMmU2N2Rm
  username: YWRtaW4=
EOF
$ oc create -f mysecret.yaml
2.Create app from image php:5.6 -> Set Name: php, fill Git Repository URL -> Create
3.Go to dc/php page, click on Add config files
4.Select "mysecret" from SECRET list as Source
Set "/data/secret" as Mount Path
Select "Select specific keys and paths"
Pick key "password", set Path: prop/secret.password
Click Add
5.Go to dc/php page, check volume info

Actual results:
5.Could see a new volume is added which type is set as "secret"
Type: secret (populated by a secret when the pod is created) 
Secret: mysecret 

Expected results:
5.Except for basic info about volume, should also list specific keys and paths we defined, should add this line in volume info
Key to File: password -> prop/secret.password


Additional info:
When we add values from config maps as volume and define specific keys and paths, keys and paths will be shown in volume info as following:

<volume-name> 
Type: config map
Config Map: special-config
Key to File: special.how → prop/configmap.how
Key to File: special.type→ prop/configmap.type
