AEMaaCS version information: being able to determine current version, latest version and being able to upgrade envrionments (dev) though CLI

**Is your feature request related to a problem? Please describe.**

At the time of writing AEMaaCS environment API [1] does not allow me to:
- inspect which version of AEMaaCS given environment runs
- check if the version I have is the latest
- upgrade the environment programatically. The only way to do it is via Cloud Manager Web UI (non PROD envs) or support ticket (STAGE/PROD). The latter may not be something Adobe considers doable (due to RO/RV), but we'd love to see such a feature for lower level environments. We has dozens of dev environments spread across multiple programs, so it is cumbersome to keep them in sync

**Describe the solution you'd like**

Please enhance the AEMaaCS environment API (CLI tool) to :

- be able to inspect the current version of any given AEMaaCS environment
- provide a list of versions - and the latest version (or show with the current version above IF this is the latest version (- and what the latest version is)
- Provide a means to execute an update through CLI on DEV instances

**Describe alternatives you've considered**
One can visit the Cloudmanager UI of each instance - or creating a "screen-scaping" script.
But a means though the CLI [0] and API [1] would be the way to go - IMHO.

**Additional context**

issue で参照されている Cloud Manager Environments API と aio-cli-plugin-cloudmanager リポジトリから始め、current-version、latest-version、development-environment のアップグレード操作が利用可能か確認します。CLI がサポートされているそれらの操作をプログラムから利用できるようにし、その動作を API の機能に照らして確認できれば完了です。
