[java-client][google-api-client] authentication support?

[jmini]

It seems to me that the google-api-client does not support authentication yet.

Tested with:

openapi: 3.0.1
info:
  title: ping test
  version: '1.0'
servers:
  - url: 'http://localhost:8082/'
  /ping/basicSecurity:
    post:
      operationId: pingBasicSec
      responses:
        '200':
          description: OK
      security:
        - httpBasic: []
  /ping/bearerSecurity:
    post:
      operationId: pingBearerSec
      responses:
        '200':
          description: OK
      security:
        - bearerAuth: []
components:
  securitySchemes:
    httpBasic:
      scheme: basic
      type: http
    bearerAuth:
      scheme: bearer
      bearerFormat: token
      type: http

For simple schemes (basic, bearer) the workaround is - to use HttpRequestInitializer when creating ApiClient.
E.g.:

HttpRequestInitializer initializer = request
                -> {
            request.getHeaders().setAccept("application/json");
            request.getHeaders().setAuthorization("Bearer " + token);
        };

        ApiClient client = new ApiClient(
                BASE_URL,
                null,
                initializer,
                null
        );
