Google Secret Manager, Field Option

Feature Request

Is your feature request related to a problem? Please describe.

Kubernetes External Secrets Operator and many other tooling ecosystems encourage the use of json as the secret payload within the google secret manager. Teller is unable to unwrap or map these to env variables.

Describe the solution you'd like

Similar to other providers such as the AWS Secret manager provider I would like the option to pass a field attribute which would treat the payload as a map and allow me to map the K:V

lets say the contents of is {"MG_KEY":"shazam", "SMTP_PASS":"mailman"}

providers:
  google_secretmanager:
    env:
      SMTP_PASS:
        path: projects/<some project>/secrets/<some secret>/versions/1

currently it would return SMTP_PASS={"MG_KEY":"shazam", "SMTP_PASS":"mailman"}

providers:
  google_secretmanager:
    env:
      SMTP_PASS:
        path: projects/<some project>/secrets/<some secret>/versions/1
        field: SMTP_PASS

this should result in teller env returning SMTP_PASS=mailman
