feat(jans-cedarling): implement toggle for Workload and User principals

[rmarinn]

---

Description

We need to implement the following bootstrap configs:

• CEDARLING_USER_AUTHZ: Enables Cedar engine authorization for a User principal.

• CEDARLING_WORKLOAD_AUTHZ: Enables Cedar engine authorization is queried for a Workload principal.

• Development target issue

target issue: refactor(jans-cedarling): make all tokens optional when calling Cedarling::authorize #10408

• Implementation Details

To be able to make tokens optional when calling Cedarling::authorize, creating user and workload entities would also need to be optional since it's possible to create a Workload entity without creating a User entity depending on the given tokens and vice-versa.

To control if an Entity is required or not, the following bootstrap properties will be implemented

• CEDARLING_USER_AUTHZ: Enables Cedar engine authorization for a User principal.
• CEDARLING_WORKLOAD_AUTHZ: Enables Cedar engine authorization is queried for a Workload principal.
