Go get takes a long time

[cuminandpaprika]

In a fresh install, go get seems to take 6 minutes to get all dependencies

Replicate:

• docker run -it golang:alpine3.11 /bin/sh
• apk add --no-cache git
• cd ..
• go get -u -v github.com/anz-bank/sysl-catalog

Notably, the modules that take the longest seem to be

• github.com/anz-bank/sysl-catalog
• github.com/go-openapi/swag
• github.com/gohugoio/hugo

Looking in the commit history, perhaps we can reduce the repo size of sysl-catalog.
In addition, we could look at replacing the github.com/gohugoio/hugo import with something smaller

Running goweight https://github.com/jondot/goweight produces the following output, which is quite enlightening and gives a list of targets to trim down
