Allow setting application features in deployment #3522
Description
When doing a "cf push" I am able to add information such as a manifest using -f flag.
I would like to add a flag for application features -
https://v3-apidocs.cloudfoundry.org/version/3.195.0/index.html#update-an-app-feature
something like:
cf push --features '{"file-based-vcap-services":enabled}'
This is important as it's not something that is opened in the manifest.
although I think it should have been.
What's the user value of this feature request?
The developer using the CLI can push the application in a ready state without needing to do a restart.
Who is the functionality for?
Operations and developers that are using the cloud foundry platform.
How often will this functionality be used by the user?
Since we use blue-green deployment it will be used massively.
Who else is affected by the change?
There is no affect on whoever is not using the new flag.
Is your feature request related to a problem? Please describe.
The problem is that application features are not exposed in the manifest of an app, I can't change them using a manifest.
Describe the solution you'd like
cf push --features '{"file-based-vcap-services":enabled}'
Describe alternatives you've considered
Additional context
This feature request is related to the new binding feature: file-based-vcap-services which from my perspective should be also configurable in the manifest but unfortunately it's not.
