Unable to have multiple CesiumWidets on the same page in 3d-tiles branch

[hpinkos]

In this example, I'm creating a new CesiumWidget for each of 4 containers. However, the globe doesn't render in two of them. This example works in master.

<style>
    @import url(../templates/bucket.css);
</style>
<table id="cesiumTable"></table>
<div id="loadingOverlay"><h1>Loading...</h1></div>
<div id="toolbar"></div>

var widgets = [];
var rows = 2;
var cols = 2;
var table = document.getElementById('cesiumTable');
table.innerHTML = '';
for (var i = 0; i < rows; i++) {
    var tr = document.createElement('tr');
    table.appendChild(tr);
    for (var j = 0; j < cols; j++) {
        var td = document.createElement('td');
        tr.appendChild(td);
        var div = document.createElement('div');
        div.style.height = '200px';
        div.style.width = '400px';
        td.appendChild(div);
        widgets.push(new Cesium.CesiumWidget(div));
    }
}

This is a bug related to the RequestScheduler. The scheduler budgets are stored at global scope but the budgets are reset in Scene, which would get called four times and mess up the budgets. If there is a good way to call RequestScheduler.resetBudgets just once per frame outside of any cesium widgets, that would be the fix.

Also the request scheduler architecture has potential to change with @austinEng's HTTP2 testing.

This should be fixed before 3d-tiles is merged into master.

Already fixed in #5308?
