tests: Add stress tests for network namespaces

These test specific combinations of TCP/UDP/IPv4/IPv6/veth/loopback
for all the kernels.

Tests take quite a while to run so there are two new labels:
'kernel' and 'kernel-extra'. 'kernel' runs the more important
tests for the two kernels we care most about. 'kernel-extra'
are additional tests for completeness.
