Add `CONFIG_NAME` to configs Runtime configurations apply to a certain network and the name of that network is useful for humans such that they can talk about it. Some of the existing configs already include a `CONFIG_NAME` toggle - might as well add it here as well and avoid some confusion - this name above all becomes useful in the beacon API. By extension, the `CONFIG_NAME` config will appear in the beacon api as a result of being defined here. 2021-12-29 11:40:16 +00:00			`# Free-form short name of the network that this configuration applies to - known`
