This PR addresses #40 as well as implements the /healthz check

Glad to see this shaping up.

Just a quick one - are you using prune with dep? I saw sample functions and other code I didn't expect in the PR.

Signed-off-by: should generally be a name too like "Alex Ellis"

[acornies]

Thanks for the pointers. I'm relatively new to Golang dev in general so any help is appreciated. I'll amend those commits.

I'm just using dep ensure after updating the faas dependencies. I'm guessing we should use the [prune] directive in the Gopkg.toml?

[alexellis]

Yes - see how prune is used in the OpenFaaS repos for faas-netes for example in Gopkg.toml then rm -rf vendor and run dep ensure again. You may have to reset the commits to prevent them recording all the files coming and then being removed again.

Feel free to ask on OF Slack if you need help with git.

[acornies]

Rebased commits and fixed up commit message with sign-off.

Looks good to me, only comment would be to add the annotations stuff to the docs but I will merge and add that.

Nice work @acornies
