Add totalMemory in config for trace graph (jaegertracing#1262)

Trace graph has a problem to renders large traces (with ~15K+ spans),
and gives the error "Cannot enlarge memory arrays". Need to give users
flexibility to control the totalMemory of LayoutManager used for
TraceGraph.

Trace graph has a problem to renders large traces (with ~15K+ spans),
and gives the error "Cannot enlarge memory arrays". This can be fixed by
providing a larger number of memory when initializing the
`LayoutManager` in trace graph, like below:
```
// default 16MB
this.layoutManager = new LayoutManager({ totalMemory: 33554432, useDotEdges: true, splines: 'polyline' });
```
But instead of hardcoding the memory value in code, we want to give
users the flexibility to control the totalMemory of LayoutManager for
TraceGraph.
