# kubectl_retry calls `kubectl` with the passed arguments. In case of a
# failure, the `kubectl` command will be retried for `KUBECTL_RETRY` times,
# with a delay of `KUBECTL_RETRY_DELAY` between them.
#
# Upon creation failures, `AlreadyExists` and `Warning` are ignored, making
# sure the create succeeds in case some objects were created successfully in a
# previous try.
#
# Upon deletion failures, the same applies as for creation, except that
# NotFound is ignored.
#
# Logs from `kubectl` are passed on to stdout, so that a calling function can
# capture it. During the function, logs are written to stderr as to not
# interfere with the log parsing of the calling function.
