introduced a bug by overriding `log` with the log created by a builder,
resulting in all logs produced by `controller-runtime` having
`controller`, `controllerGroup` and `controllerKind` set to the last
created controller.

🐛 don't override global log in builder

When starting a single test environment [1], the control plane start-up
logic [2] launches an etcd and kube-apiserver process. The start-up
logic needs to bind these processes to multiple ports, and when none are
configured in advance, the logic looks for unused ports, and then
creates files in the user cache directory to reserve them (for example,
[3]).

However, the same logic used to reserve ports  also has logic that
deletes files corresponding to "outdated" ports [4].

Therefore, if there are multiple processes/threads starting a test
environment, they may sometimes end up trying to delete the same file
which causes a "file not found" error.

This commit adds logic so that trying to start multiple test
environments does not fail if more than one tries to delete the same
file corresponding to an outdated port.

🐛 Fix issue with starting multiple test envs

Some operators might want to respect cluster-wide TLS ciphers for example,
which means that these will eventually have to be passed down to the webhook server.
