This is an alternative approach to #18155 for injecting env vars into container configurations.
With this PR, anywhere parameters are allowed, one can use `%env(ENV_VAR)%` to inject a dynamic env var. Additionally, if one sets a value to such parameters in e.g. the `parameter.yml` file (`env(ENV_VAR): foo`), this value will be used as a default value when the env var is not defined. If no default value is specified, an `EnvVarNotFoundException` will be thrown at runtime.
Unlike previous attempts that also used parameters (#16403), the implementation is compatible with DI extensions: before being dumped, env vars are resolved to uniquely identifiable string placeholders that can get through DI extensions manipulations. When dumped, these unique placeholders are replaced by dynamic calls to a getEnv method..
