Websockets instead of plain requests

So we can get things like live build status, etc as well as a cleaner log implementation

However, not sure if actually needed

How the CLI prints messages:
https://github.com/ubclaunchpad/inertia/blob/master/deploy.go#L204

We want this on the daemon, and instead of printing it, broadcast each line over websockets

The daemon logger handles writing: https://github.com/ubclaunchpad/inertia/blob/master/daemon/inertia/logger.go

That logger manages writing to multiple sources and broadcasting HTTP request successes/failures. Whether it'll be needed going forward is up for debate

FlushRoutines are used together with the logger for parsing the raw Docker bytestream: https://github.com/ubclaunchpad/inertia/blob/master/common/util.go#L69

Example usage: https://github.com/ubclaunchpad/inertia/blob/master/daemon/inertia/project/build.go#L91
