A way to inherit/replicate an environment

[vmatsiiako]

Feature description

Now that we are going to have custom environments it would be great to be able to inherit or replicate environments. For example, when I add a secret to one environment, I'd love to have the option to add it to the other ones too. Or, when a user creates an environment, it would be awesome to be able to fill in secrets based on a template from an existing environment (a user would only need to change secret values).

Why would it be useful?

Saves people a lot of time and creates more 'automations'. Makes it easier to keep track of everything.

Additional context

I'm not sure how exactly it should look like yet, so open to any ideas!
