Show traffic split metrics from sources in all namespaces (#3967)
Fixes #3562 

When a pod in one namespace sends traffic to a service which is the apex of a traffic split in another namespace, that traffic is not displayed in the `linkerd stat trafficsplit` output.  This is because when we do a Prometheus query for traffic to the traffic split, we supply a Prometheus label selector to only select traffic sources in the namespace of the traffic split.

Since any pod in any namespace can send traffic to the apex service of a traffic split, we must look at all possible sources of traffic, not just the ones in the same namespace.

Before:

```
$ bin/linkerd stat ts
NAME           APEX     LEAF       WEIGHT   SUCCESS   RPS   LATENCY_P50   LATENCY_P95   LATENCY_P99
webapp-split   webapp   webapp       900m         -     -             -             -             -
webapp-split   webapp   webapp-2     100m         -     -             -             -             -
```

After:

```
$ bin/linkerd stat ts
NAME           APEX     LEAF       WEIGHT   SUCCESS      RPS   LATENCY_P50   LATENCY_P95   LATENCY_P99
webapp-split   webapp   webapp       900m    80.00%   1.4rps          31ms          99ms        2530ms
webapp-split   webapp   webapp-2     100m    60.00%   0.2rps          35ms          93ms          99ms
```
