title: springdoc-openapi apply default global SecurityScheme possible?
body: <p>I have the following <a href="http://docs.swagger.io/swagger-core/v2.1.1/apidocs/io/swagger/v3/oas/annotations/security/SecurityScheme.html" rel="noreferrer"><code>SecurityScheme</code></a> definition using springdoc-openapi for java SpringBoot RESTful app:</p>
  
  <pre><code>    @Bean
      public OpenAPI customOpenAPI() {
          return new OpenAPI()
                  .components(new Components().addSecuritySchemes("bearer-jwt",
                   new SecurityScheme().type(SecurityScheme.Type.HTTP).scheme("bearer").bearerFormat("JWT")
                  .in(SecurityScheme.In.HEADER).name("Authorization")))
                  .info(new Info().title("App API").version("snapshot"));
      }
  </code></pre>
  
  <p>Is it possible to apply it globally to all paths, without having to go and add <a href="http://docs.swagger.io/swagger-core/v2.1.1/apidocs/io/swagger/v3/oas/annotations/security/SecurityRequirement.html" rel="noreferrer"><code>@SecurityRequirement</code></a> annotations to <a href="http://docs.swagger.io/swagger-core/v2.1.1/apidocs/io/swagger/v3/oas/annotations/Operation.html" rel="noreferrer"><code>@Operation</code></a> annotation everywhere in the code?</p>
  
  <p>If it is, how to add exclusions to unsecured paths?</p>
