New Profile: Discovery Service Specification SSP-002 READ Only

[BirgitBoss]

What is missing?

Describe the problem in short sentences, add a minimal example if possible
(Standard CX-0002 in Catena-X) In Catena-X it is a MUST to implement the GET operations, however write and delete is just optional:

The API MUST be implemented as specified for the profiles: [...] "Discovery Service Specification V3.0 Profile SSP-001 [...] DELETE and POST operations of Discovery Interface are optional to be implemented"

How should it be fixed?

Add READ-ONLY Profile for Discovery (similar to Registry READ-ONLY)

• [x] I have signed the required Developer Certificate of Origin (DCO) already.

Let's add it with the V3.1.0 release.
