[uss_qualifier] Replace has_private_address by new resource TestExclusionResource

[mickmis]

Address #739

Notes:

• Many files are changed but most are configurations and suites propagating the new resource into the scenarios that use it
• For NetRID DSS resources the field has_private_address is kept but only because it is used to determine the value of local_debug. A soon-to-follow PR will move local_debug into TestExclusionsResource to clean that up completely.
• Behavior change: the 'publicly adressable' check is now skipped, before it succeeded when the flag was set.
• For the NetRID DSS interoperability scenarios, the severity of the 'publicly adressable' check is now set through the .md file and is now high (before: medium).

Switching to draft until CI errors are resolved. OK
