This series extends the "nsholder" tool we use in the tests to
"nstool" with some more features. In particular it allows entering an
established namespace with capabilities intact, and it allows entering
them with less verbose options than nsenter.
For now this only gives a modest simplification of the tests, but it
should enable more in future.
I haven't managed to get all the way through the testsuite with this:
it's wedging in the IPv4 UDP throughput tests, but that's happening
for me with the main branch too. I'll debug that, but I don't want to
delay this series on that for now.
