feat: introduce API leveling, post_training to v1alpha

Browse source 
Rather than have a single `LLAMA_STACK_VERSION`, we need to have a `_V1`, `_V1ALPHA`, and `_V1BETA` constant.

This also necessitated addition of `level` to the `WebMethod` so that routing can be handeled properly.

move post_training to `v1alpha` as it is under heavy development and not near its final state
