Move finagle and grpc projects to a dedicated repo

[olix0r]

• create a new repo with copies of linkerd's finagle and grpc subprojects. The finagle project houses our h2 implementation and the grpc project has the protoc plugin, runtime library (that depends on the h2 impl, etc).
• We'll probably need help putting together an SBT plugin.
• Once we can publish all of this from the new repo, we'll update the linkerd repo to depend on these libraries.

any update on this @olix0r ?

Any update here @olix0r ? Novolabs is more than willing to allocate some development cycles to help in any way we can with this.

Sorry for the radio silence on our end. We've been focused on a number of issues that touch finagle-h2, and moving this subproject out of this repo would add significant friction to our debug cycle...

I am not against this change in general, though I think it is ill-advised to do this before these features are considered stable in linkerd.

any update here? What about a module inside this repo so you don't need to move anything and still build normally (just a separate subproject)?

[oscar-stripe]

actually, maybe you already did this?

[adleong]

The finagle-h2 and grpc projects are already sbt subprojects in the Linkerd repo that can be built individually. @oscar-stripe is that sufficient or are you still interested in them being moved into a separate repo?
