Make SCS GX Credential Generator Gaia-X Compliant

[anjastrunk]

As a Cloud Provider, I want to offer my Openstack based IaaS cloud in a Gaia-X compatible Federation. In Gaia-X, each Service Offering MUST be describe by a Gaia-X Credential, which is authored by Cloud Provider.

SCS Self-Description Generator facilitates the creation of Gaia-X credentials for Openstack based IaaS clouds, by generating parts of it, automatically. Howver, output of Self-Description Generator is not Gaia-X compliant.

This issue acts as epic for all issues, related to make SCS self-description generator Gaia-X compliant.

Process feedback Notes from reviewing the SD attributes:

• Virtualized CPU types: It might be of limited use to reference exact model names, rather characterize properties (generation, speed, insn set extensions, ...)
• NICs: Virtual NICs are almost unlimited, but there may be a limited amount of hardware-accelerated
  NICs (using SR-IOV and multiqueue features) available -- these may need to be added to SCS flavor
  naming.
• Other extension hardware like FPGAs need to be specified
• Tenant isolation needs a list of criteria. Virt OK? V(x)LANs OK? Shared storage cluster OK? ...
• Availability Zones: Provider needs to create transparency over what it means. Fire protection zones?
  Power supply zones? Internet connectivity zones? Minimal and maximal physical distance? Network
  latency distance?

Gaia-X Self-Description is renamed in Gaia-X Credential. See Architecture Doc .

We should get rid of the old term "Self-Description" in our documentation. I update user story of this issue.
