REST client needs to expose HEAD

[stephenmichaelf]

The HTTP client does, we need the REST one to also. It will be consumed in the node api.

We are going to handle this in generation for the node api.

@stephenmichaelf Do you think this is worth having for other users of the library? If not I'll close my PR, but its a pretty straightforward change I think.

I think it's an http concept - not a rest one ... the rest layer is very rest/resource oriented. So the generation can call http head. This library is layered but it's expected to use the public http layer for http type operations.

Ok, that makes sense, I'll close the PR.
