Describe the new feature

Hello all,

We have been using unleash in a professional project based in an hexagonal architecture where we separate and put every app configuration in yaml param file and use those files to configure features toggles to enable/disable features using unleash (this bundle), to ensure using the same methodology before unleash I suggested and developed an Env processor to replace Env variables by unleash using yaml syntaxe which is a good way to create one parameter connected to unleash variable and use it everywhere in the app.

%env(unleash:feature_name)%

to make a default value we just need to declare a default value for the env

 parameters:
     %env(unleash:feature_name)%: false

I suggest to integrate this possibility into this bundle while we can enable/disable this feature by extension parameter.

You may take a look on my created pull request (marked draft) : #60
