Add end user documentation of AirshipCTL commands to readthedocs about airshipctl

[alexander-hughes]

Seems this story may not be needed, or needs to be fleshed out better.

There's a couple options in generating go documentation - first is an automatic process is triggering documentation builds on https://godoc.org/opendev.org/airship/airshipctl

alternatively there is a way to generate html files from godoc directly that could be uploaded to a web server:

make godoc
wget -r -np -N -E -p -k http://localhost:8080/pkg/opendev.org/airship/airshipctl/

upload the downloaded files from the wget command

I think we should probably just host the source docs on godoc.org.

We do have Sphinx docs inside of our project currently though. It seems we should host these at RTD still.

The stuff on godoc.org can be more like the technical docs and our stuff on RTD can be more pointed towards end users.

Need to configure zuul roles, and change Makefile etc to get this working
