Delete federation system namespace from all the federated clusters.

Browse Source 
This is a big hammer. `kubefed join` creates federation-system namespace
in the joining clusters if they don't already exist. This namespace
usually exists in the host cluster and hence cannot be deleted while
unjoining. So in order to be safe, we don't delete the federation-system
namespace from any federated cluster while unjoining them. This causes
a problem in our test environment if certain resources are left in the
namespace. Therefore we are deleting all federation-system namespace in
all the clusters.
