feat: config to disable pathParts parsing

[klopfdreh]

Solves https://github.com/spring-cloud/spring-cloud-common-security-config/issues/94

With this PR you can disable the parsing of the pathParts by applying this configuration:

    spring:
      cloud:
        dataflow:  
          security:
            authorization:
                user_login:
                  map-oauth-scopes: true
                  parse-oauth-scope-path-parts: false
                  role-mappings:
                    ROLE_CREATE: '/F///FUNC/2000803037///X'

If the name of the property is ok for you I need to rename it to „parseOauthPathParts“ with lower A. I am going to do this, tomorrow. The name also reflects back the scope like „mapOauthScopes“, now.

Edit: maybe „parseOauthScopePathParts“ would be even better. I would not mention that this is happening during the mapping, because this is obvious because the property is applied to the class ProviderRoleMapping so you can assume that the parsing is done during the role mapping.

I think that will work well.
