If we get a not found error, the issuerObject will be empty.
Because of that, information like the issuer's name (which exists in the reference) and the issuer's namespace will not be passed to IgnoreIssuer.

Originally, my thinking was that issuers could be ignored using IgnoreIssuer for the check command and IgnoreCertificateRequest for the sign command. WDYT cc @ThatsMrTalbot

When I was writing an example to check the UX of issuer-lib for internal issuers IgnoreCertificateRequest was a pain.

For each CertificateRequest you have to check if its an Issuer or a ClusterIssuer, load the correct type, then check if its one we care about.

Having IgnoreIssuer apply to the signer controller makes this so much easier

}

return result, statusPatch, nil // apply patch, done
} else if err != nil {
logger.V(1).Error(err, "Unexpected error while getting Issuer")

if r.IgnoreIssuer == nil {
statusPatch.SetUnexpectedError(err)
}

return result, nil, fmt.Errorf("unexpected get error: %v", err) // requeue with backoff
}

if r.IgnoreIssuer != nil {
ignore, err := r.IgnoreIssuer(ctx, issuerObject)

if err != nil {
logger.V(1).Error(err, "Unexpected error while checking if Request should be ignored")
return result, nil, fmt.Errorf("failed to check if Request should be ignored: %v", err) // requeue with backoff
