Support to scope definition when using KeycloakInstalled (desktop usage)

Description

If you want to secure java desktop applications, the documentation recommendation is that you can use org.keycloak.keycloak-installed-adapter. Nonetheless, there aren’t any way to define scopes (or if there is, it isn’t documented).

Currently, to define custom scopes, you’re need to reimplement KeycloakInstalled.

I made this following modifications: Replace this following lines: https://github.com/keycloak/keycloak/blob/c31d37ddf1c3e3529e761800a6842fdbf25ba931/adapters/oidc/installed/src/main/java/org/keycloak/adapters/installed/KeycloakInstalled.java#L241 https://github.com/keycloak/keycloak/blob/c31d37ddf1c3e3529e761800a6842fdbf25ba931/adapters/oidc/installed/src/main/java/org/keycloak/adapters/installed/KeycloakInstalled.java#L468 to this one:

.queryParam(OAuth2Constants.SCOPE, Optional.ofNullable(deployment.getScope()).orElse(OAuth2Constants.SCOPE_OPENID))

And, when specify the scope,

keycloak = new MyCustomKeycloakInstalled(targetStream);
keycloak.setLocale(Locale.getDefault());
keycloak.getDeployment().setScope(OAuth2Constants.SCOPE_OPENID + " mycustomscope");

Probably a better alternative is using keycloak.json configuration file. But unfortunately Jackson Parser throws an exception.

Looks like a valid requirement. We can probably just add a setScope method to do that, right?

If you are able to send a PR, I’m glad to review and merge.

Cool, I added a PR a few days ago. Have a look when you have time.
