feat(envrc): Loading and timing (#16458)

* feat(scripts): Auto-set cluster from aws login information

* Add .envrc.kube for auto-cluster selection

* Rename .envrc.podman

* Add timing function

* Better timekeeping

* Cleanup

* Clearer intent, less piping

* Corrected timekeeping

* Revert .env* to main

* Rename .envrc.podman

* Ignore all .env.*

* Source-if-exist kube and podman

* No-oneliner

* Refactor to only use required tools (kubectl)

* Only return in podman

* Use sed instead of grep -P

* No -P

* Timed .envrc
