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**
- none-

Start with the Cloud Manager Environments API and the aio-cli-plugin-cloudmanager repository referenced in the issue, checking whether current-version, latest-version, and development-environment upgrade operations are available. Done means the CLI can expose those supported operations programmatically, with behavior confirmed against the API capabilities.
