Adding sensitive flag to secrets files
I've added the sensitive flag to the most obvious secret files holder.
We should decide if we want to hide also the database.yml
and likes because it can contain password and if we want also to hide gitlab.yml
content as it may contain app secrets for OAuth authentication providers.
Closes #2133 (closed)
