GEP: Conformance Profiles

[shaneutt]

In the community we've referred to the concept of adding "conformance levels" or "conformance profiles" to Gateway API for quite some time.

NOTE: We've chose conformance profiles over conformance levels in order to not be confused with support levels.

The concept is to have named groupings of conformance tests that can be easily selected for implementations, and correspond with the "category" of implementation. Initially we would like conformance profiles covering these "categories":

• Layer 7
• Layer 4
• Mesh

Profiles should also include options to create conformance testing reports which can be submitted back to the Gateway API project.

@shaneutt this would be a topic of SIG Arch meeting where we discuss Conformance topics. Next meeting is tomorrow.

@Riaankl sounds good, I will bring this up in that forum as we progress. However I will not be available for the meeting tomorrow, so I'll intend on a later date meeting which will provide some time for this to grow anyhow.
