OAuth librabry don't remove newline char at the end of secret

[Frawless]

After a discussion with @mstruk we think the library should truncate \nat the end of secret. We hit this during refactor of Strimzi oauth tests.

For example: printf "%s" "team-a-client-secret" | base64 echo "team-a-client-secret" | base64

return different values because \n at the end of encoded data.

This issue is still present and I hit it today. Is it possible to give it a priority?

Unless there is a clear standard which says that whitespaces cannot be part of the secret I do not think we should remove them.
