Leverage `schemars` to generate a JSON Schema from our structs for
configurations and those occurring within them.
The output of `rad config schema` can be used by editors to provide a
smoother editing experience for the configuration file. Discovery
attributes (both keys and values) is greatly improved with the schema
helping in the background.

The `Editor` is very useful for correctly opening a text editor and making changes
to some initial input. The current use of `Editor` is only for getting input for
commets.
However, it would also be useful for opening up a text editor on some other
existing files or text, for example, in the command `rad config edit`.
The `Editor` struct was changed to have two new options, `truncate` and
`cleanup`, to allow the user of the struct to dictate whether existing text is
truncated, and if the underlying file should be remove.
The original `new` method is now named `comment`, mimicing the existing
construction of a temporary `RAD_COMMENT` file.
The new version of `new` accepts any file for the `Editor` and will open it
without truncating or removing the file.
`Editor` is now used for the `rad config edit` command.
Adds `set`, `add`, `remove`, `delete` to `rad config`.
Note that the changes will affect the configuration file, but not the
running instances. For changes to be reflected in the running instances
the node would need to be restarted.
