Hello Aras! Is ScriptableRenderLoop/HDRenderPipeline going to be shipped in Unity 2017.x?
That's the plan, yes.
You can already use an older version of it (at your own risk) in current Unity 5.6 betas; the github project contains information on which revisions of it should be used.
Basic things are already working fairly well; the largest piece of the missing puzzle is nice UX for all the things. For example, how built-in scene view rendering debug modes should interact with debug modes provided by the HD render pipeline itself. Where various settings should be put in the UI. etc. etc.
