[x] Clarify the language to reflect what simple_deploy actually does in configuration mode.
[x] Configuration mode: create the minimum set of resources necessary to carry out configuration.
[x] Automation mode: carry out the entire deployment process.
[x] Add a note to "Quick Start: Configuration-only deployment" section in support_new_platform.yml, to clarify what kinds of actions we typically take in configuration-only mode.
[x] Maybe change "configuration-only" to simply "configuration", to stop implying that we don't create resources in this mode.
Not worth changing at the moment. "Configuration-only" is still meaningful, as it configures the project without making the actual push/deployment.
Specifically, the language here is inaccurate.
simple_deployactually does in configuration mode.
