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

I 'd like to be able to declaratively set log level for gloo-fed components.

Describe the solution you'd like

Helm chart option as we do for other gloo components:

gloo-fed:
  enabled: true
  glooFed:
    logLevel: warn
  glooFedApiserver:
    enable: true
    logLevel: warn

Describe alternatives you've considered

Using customEnv chart option to set env variables, but it's ignored.
