Configuration: 'issuer': unknown field

Hi !

I am trying to get this plugin working in DB-less mode (I am going to deploy on kubernetes so I want to have all the configuration fixed in a declarative way)

I have installed the plugin in a docker image but the configurations are not recognized.

The error:

kong     | 2020/04/15 15:49:33 [error] 1#0: init_by_lua error: /usr/local/share/lua/5.1/kong/init.lua:431: error parsing declarative config file /usr/local/kong/declarative/kong.yml:

I am new in kong so sorry if it's more a kong issue than a kong-oidc issue.

For informations I tried to reproduce what I found here: https://github.com/nokia/kong-oidc/issues/136

Since there is no documentation in Kong about plugin config in declarative file.
