Pool-Auth: Configurable Permission Names

[nicoprow]

Currently the Pool endpoints are secured via fix-named permissions. The Pool properties should offer to configure the name of permissions. Also the BpdmSecurityConfigurerAdapterImpl should secure the endpoints in the following way:

Read Business-Partner Permission: Default "read_pool_partner_data":
Access to all business partner GET endpoints or POST search/filter endpoints (Every access to business partner data and changelog that does not update the data itself.)

Write Business-Partner Permission: Default "change_pool_partner_data":
Access to all business partner endpoints that add or update business partners (POST and PUT endpoints for changing the business partners)

Read Meta-Data Permission: Default "read_meta_data":
Access to all GET meta data endpoints

Write Meta-Data Permission: Default "change_meta_data":
Access to meta data endpoints updating or creating meta data

Opensearch Admin Permission: Default "manage_opensearch":
Access to all endpoints for managing the opensearch
