Hi, I'm wondering if there is a way to set configuration values (secrets especially) from code using Pulumi's APIs? I know I can always invoke a shell command but that seems silly if there is a programmatic access to this somewhere. The use case in this regard would be to ask for initial users to be created into a system. Passwords are the important part here. Sure one can just generate those and print those out but in this case it would be useful to be able to type the preferred passwords in. Why I'm thinking using configuration mechanism with this is because this would allow checking if those have already been set or not when executing the code for the first time. If they are in remote state then this would apply over all use cases no matter the developer - meaning initial users don't get created several times.
