Description of problem:
When we change deployment strategy from Recreate to Rolling, select "No" then previous lifecyle hooks will be cleared and not shown on web console, but in Command Line, we could still see the lifecyle hooks when use 'oc describe dc <dc_name>'

Version-Release number of selected component (if applicable):
latest origin-web-console(latest commit is PR #715 from spadgett/metrics-pod-uid)

How reproducible:
Always

Steps to Reproduce:
1.Create app
# oc process -f https://raw.githubusercontent.com/openshift/rails-ex/master/openshift/templates/rails-postgresql.json |oc create -f -
2.Wait for #1 rails-postgresql-example build complete and #1 rails-postgresql-example deployment finish
3.Go to Applications -> Deployments -> rails-postgresql-example -> Actions -> Edit
4.Change Strategy Type to Rolling, select "No" in the dialogue
Timeout & Maximal Unavailable Pods & Maximal Surge Pods value are cleared
5.Click advanced strategy options
Update Period & Interval is also not set with value
No Pre Lifecycle Hook
No Post Lifecycle Hook
6.Set follow values and Save
Timeout: 500 seconds
Update Period:2 seconds
Interval: 2 seconds
Maximal Unavailable Pods:30%
Maximal Surge Pods: 30%
7.Check deployment hooks via CLI
# oc describe dc rails-postgresql-example


Actual results:
7. # oc describe dc rails-postgresql-example
....<snip>...
Strategy:	Rolling
  Pre-deployment hook (pod type, failure policy: Abort):
    Container:	rails-postgresql-example
    Command:	./migrate-database.sh
Pre-deployment hooks is still shown in output, indeed when changing Recreate to Rolling, all lifecycle hooks should be cleared if we select "No"

Expected results:
7. All lifecycle hooks should be cleared when we select "No" (means we don't keep parameter from Recreate strategy) in changing Recreate to Rolling
In step5, web console didn't show any lifecycle hooks after we selected "No"
