Subject Re: Using Rust for the KnativeWhisk controller

IMO, one of the largest barriers to getting more (back-end) developers into OW has been the
use of Scala (sig. learning curve will not even consider mounting) is by implementing in languages
where the pool of active developers is lower.  It seems that nearly 100% of Serverless technology
"in the open" is being done in GoLang.  If we wish to attract developers from Knative, OpenFaaS,
Kubeless, Fission, Fn, IronFunctions, etc., they ALL use Go (which is not surprising as everyone
is more-or-less looking at a Kube stack, also Go, for CN apps with Serverless being a subset).

Personally, after experiencing Go, for wskdeploy/CLI it was a joy to learn (despite some tooling
annoyances) and have listed it as a top requirement developers training. In fact, I had assumed
that as we seek to mainstream on a Kube deployment we would want to unify around Go to continue
to be relevant in the Serverless developer community in order to lower the barrier to entry/growth.

My 2 cents.

let me know because that would be my preferred choice.
