What this PR does / why we need it:

It is possible to specify plugin init config like:

plugins:
  - name: k8saudit
    library_path: libk8saudit.so
    init_config:
      maxEventSize: 262144
      sslCertificate: /etc/falco/falco.pem

or

plugins:
  - name: k8saudit
    library_path: libk8saudit.so
    init_config: '{"maxEventSize": 262144, "sslCertificate": "/etc/falco/falco.pem"}'

But json schema didn't allow that and only accepted a string. This PR adds the map option to the schema.

cc @FedeDP @alacuku I would add this to 0.39.0 if you agree as Falco is currently emitting warnings on valid configs

/milestone 0.39.0
