Feature Request: Add support for optionally passing in environment variable blocks

[alanquillin]

Currently, you can only pass in extra environment variables as key value pairs in the values file:

env:
    foo: bar

however, this does not help if you need to pass in variables from config maps or secrets. It would be super helpful to be able to add something like the following to the values:

extraEnvs:
- name: SECRET_USERNAME
   valueFrom:
      secretKeyRef:
        name: mysecret
        key: username

The only way I have found is to create a secret and add it as the externalSecrets, however, this then requires me to manage ALL the environment variables for all the secrets, which is not ideal.

Hi! #35 (release v4.7.0) added an option to let you pass extra secrets to env vars, does this solve your problem?
