Subject: [PATCH] tests: Add namespace stress tests

These tests run individual and a mix of namespace stress tests
mostly around networking and unix domain sockets where either
the client or the server of socket echo application is run inside
a container in different configurations:
- different protocols
- short or long lived connections
- different levels of concurrency

Tests are only run if the 'kernel' label is specified and more
detailed tests are run if the additional 'kernel-extra' label
is specified.
