Snapcraft: create how-to documentation for review-tools

[degville]

Write a how-to guide on using review-tools to check a snap is consistent and secure.

Background

The review-tool command can be used to test whether a freshly built snap will pass Store tests permitting the snap to be published. The Store runs reviews tools whenever a new snap is uploaded. The following is a common command, for example:

review-tools.snap-review cameractrls_0.5.6-0-gd8136d1_amd64.snap 

This how-to should cover how to install the review-tools snap, how its most important functions are accessed, and how some of the most common problems could be mitigated.

Prerequisites

You will need some experience building snaps.

Hello @degville , thanks. Working on this!

Hi @degville ,

I have a draft ready but would welcome your eye, and especially suggestions particularly on the other commands/errors/warnings etc.

I have a draft PR that I'd be happy to improve.

Thanks
