* feat(backend): add requireKey option to backend
This option will prevent `autorestic` from generating a key and will
cause it to crash instead. This is intended for use cases where you want
to provision the key yourself and don't want `autorestic` to
accidentally generate one for you.
* doc(backend): document requireKey
We restic supports multiple types of backends. See the [full list](/backend/available) for details.

## Avoid Generating Keys
By default, `autorestic` will generate a key for every backend if none is defined. This is done by updating your config file with the key.
In cases where you want to provide the key yourself, you can ensure that `autorestic` doesn't accidentally generate one for you by setting `requireKey: true`.
Example:
```yaml | .autorestic.yml
version: 2
backends:
foo:
type: local
path: /data/my/backups
# Alternatively, you can set the key through the `AUTORESTIC_FOO_RESTIC_PASSWORD` environment variable.
key: ... your key here ...
requireKey: true
```
With this setting, if a key is missing, `autorestic` will crash instead of generating a new key and updating your config file.
