Description

It's easier and faster to wait for the namespace deletion rather than resource by resource.

It also fixes a race condition that happens when you execute k8s-netperf twice without waiting for some time between executions, the netperf namespace is still in Deleting status and k8s-netperf crashes. e.g:

$ ./bin/amd64/k8s-netperf --config examples/netperf-full.yml  --debug --all
