CLI command to store credentials without actual deployment

[ThePlenkov]

Hi!

To be able to test the app in so-called hybrid mode I'm use a command like cds deploy --store-credentials. This command allows me to store credentials in db/default-env.json file which allows me to run actual service locally with access to the real HDI container.

So problem is - sometimes I do not need to deploy - I only want to have those credentials.

Let's say my model contains only artifacts already presented in db and I don't even need to deploy anything so having a command like cds store-credentials or at least allow cds deploy --dry --store-credentials to store them would help a lot.

What do you think about this?

Thanks!
