secret env vars

[aogier]

This PR allows for specifying secret env vars by either

• mounting an entire secret(s) via envFrom

  deployment:
    secretEnvironments:
      - secret1
      - secret2

• projecting specific secrets allowing eg. valueFrom in container's env stanza. An existing env value is preserved as is, but it is also allowed to be a map, ie. an invalid scalar value but a valid projection config:

  deployment:
    env:
      ACCOUNT_PROVISIONER: LDAP
      LDAP_SERVER_HOST: ldap://openldap
      LDAP_BIND_DN: cn=admin,dc=ldap
      LDAP_BIND_PW:
        valueFrom:
          secretKeyRef:
            name: mailserver
            key: LDAP_BIND_PW

everything is backwards compatible, so completely inobtrusive for existing deployments

hope this helps, ciao!
