Run the end-to-end tests in a different namespace

[cmainas]

Most of the tools that we use for our end-to-end testing allow the use of namespaces (not linux namespaces) to run the containers. Therefore, instead of running all our tests in the default namespace, we can create one only for the purpose of our end-to-end tests. Such a design would be also useful for cleaning up and making sure we do not leave any rubbish in the host of the end-to-end testing

Hi @cmainas, no active PR on this so I would like to pick it up. My plan is to create a urunc-test containerd namespace in
BeforeSuite, clean it up in AfterSuite, and pass it to all nerdctl and ctr commands. Does urunc-test work as thenamespace name?

Hello @mdryaan , the plan sounds good and the name is fine.
