**What**
- Add the ability to specify secrets as a csv
- Vendor the docker/cli/opts
- Update the guide for secrets to use the `faas-cli`
**Why**
- Allowing the csv specification of secrets gives users more control about how
those secrets are mounted into the container. This is good for things like
key rotation and for developers that are building on top of OpenFaaS.

Note, not all `alexellis/github` references should be changed, there are
a number of repos which are not part of the openfaas org, this commit
excludes those.
