discussion: experimental APIGroup for adding runtime traits

[hongchaodeng]

This has been raised up in the community meeting when we discussed #24.

Since spec is relatively stable, we want to validate ideas before making changes to spec. Usually we model some runtime functionalities as traits at first stage and then gradually move them into the spec. As a common practice, we need to agree on a standard experimental APIGroup for these kind of system/runtime traits.

My proposal is experimental.core.oam.dev/v1alpha2, where core.oam.dev/v1alpha2 matches the spec version and we add experimental prefix.

Thanks! experimental.core.oam.dev/v1alpha2 LGTM

We will need to add a section in OAM k8s runtime doc to claim what does this mean.

LGTM
