How to set user?

[node-gs]

I'm trying to use this gem with a specific user, "deploy". I can see from the docs that it says:

"secrets from your local secrets.yml are copied to the servers in your config/deploy/{environment}.rb files using the user: value. a."

I'm not quite sure what this means, or how to set the user value or if it relates to the ssh user. I'm happy to submit a pull request where the user can be specified in the task.

I've had to unpack the gem and change the string manually for now.

Would be nice to get your opinion :)
