dsh-maestro-config: Shared Configuration Service for the dsh-maestro-* Suite

`dsh-maestro-config` is a shared settings service plugin maintained by ddtcorex, designed to address the issues of fragmented configurations and high maintenance overhead across the `dsh-maestro-*` suites. It utilizes the `~/.dsh/maestro/settings.` namespace for centralized storage and is classified under the `admin-security` category. The plugin runs with the privileges of the current `dsh` process, making it suitable for sharing configurations between suites; however, users should be aware of potential security risks and are advised to refer to GitHub for installation instructions.
