forked from rook/rook

We don't need to use tini. We don't have anything in the rook operator that would either create zombie processes (no threads) or use exec (to fork). The Go binary has a really good signal handling mechanism. Closes: https://github.com/rook/rook/issues/8794 Signed-off-by: Sébastien Han <seb@redhat.com>
