[Feature] Depends on specified version of apps in App Manifests

[owenstake]

My App need to depends on specified version of some apps, how to achieve this in Manifests?

I expect some syntax like this:

...
"depends" : ["[email protected]", "[email protected]"]
...

<app>@<version> is an experimental feature.

FYI: Create manifests for specified version of apps, e.g.: versions/python38, versions/ruby27, then use them as dependencies.
