Replace Kitura-Request with SwiftyRequest, update WebSocket

[KyeMaloy97]

• Replaces Kitura-Request with SwiftyRequest
• Updated to Web Socket 1.0
• Removes some character references as per 4.0.2 deprecation of the type

This PR requires Kitura to be using the newer version of Kitura-Net (2.0) and Kitura WebSocket (1.0). This should come in an upcoming release.

@KyeMaloy97 - so this depends on an upcoming release of Kitura? I'm going to mark as WIP (work in progress) which we do for PRs that aren't ready to be merged.

@sjanuary Pretty much yea, we need Kitura to get a new release before this PR will be ready to merge.

For the SwiftBAMDC testing, I have created a branch and changed the code around to point to the correct versions to ease testing. Please use my own fork of the repo which is here: https://github.com/KyeMaloy97/SwiftMetrics and use the swift4_BAM_Test branch.

It's pointing to a specific Kitura commit instead of a specific release. I tested using branch in a Starter project and it worked for me. Let me know if you have any issues. If you use it as a dependency in a project and that project also uses Kitura, make sure Kitura's dependency in the Package.swift is set out like this:

.package(url: "https://github.com/IBM-Swift/Kitura.git", .revision("b7e4a665aa16400a63c0bb9596ba99c58d950839"))

@KyeMaloy97 please also add yourself to AUTHORS.md as part of this PR

@KyeMaloy97 thanks for making the changes I asked for yesterday. I've just re-organized the branches for SwiftMetrics and master is now the branch for Swift 4, so please could you redo your PR against master?

This got closed automatically when I deleted the swift4 branch

@KyeMaloy97 Mike showed me how to reopen this against a different branch so no need to create a new one
