[KNOX-3286](https://issues.apache.org/jira/browse/KNOX-3286) - Put
/scheduler-ui behind knox-proxy in YARN UI V2
## What changes were proposed in this pull request?
https://issues.apache.org/jira/browse/YARN-11938 integrate scheduler-ui in
YARN UIV2.
It works perfectly in a non-secure cluster.
However, in a secure cluster with KNOX:
When user view YARN UIV2
Navigate to Scheduler-UI navigation bar
It will redirect user to {knox-gateway}/scheduler-ui
Which will throw 404 status code because it is not behind knox-proxy
In secured cluster, yarn-scheduler-ui is served under /yarn-scheduler-ui
according to this ticket https://issues.apache.org/jira/browse/KNOX-3249
Thus the rewrite.xml should be updated for YARNUIV2 to put the /scheduler-ui
behind KNOX proxy to /yarn-scheduler-ui when user click on navigation bar
Scheduler UI.
## How was this patch tested?
Tested manually and it rewrite to put behind KNOX proxy
```
buildFragment: function buildFragment(dom) {
var el0 = dom.createDocumentFragment();
var el1 = dom.createTextNode(" ");
dom.appendChild(el0, el1);
var el1 = dom.createElement("li");
var el2 = dom.createElement("a");
dom.setAttribute(el2, "href",
"/gateway/cdp-proxy/yarn-scheduler-ui");
dom.setAttribute(el2, "class", "navigation-link ember-view");
var el3 = dom.createTextNode("Scheduler UI");
dom.appendChild(el2, el3);
dom.appendChild(el1, el2);
dom.appendChild(el0, el1);
var el1 = dom.createTextNode("\n");
dom.appendChild(el0, el1);
return el0;
},
```
