Bastion floating on Tide - Part 2

This post is Part two of a series on how to build a highly fault tolerant system using bastion-rs, and expose an async web api with Tide. Part one is about setting up a simple Tide server, and covers initial steps such as adding dependencies, some basic routing and the request/reply model. In Part two we will first do a bit of refactoring, and then transform our function into a bastion child.
