fluxService - update shell commands and refactor

[MorningLightMountain713]

What this pull does

• Update fluxService to use serviceHelper command runner.
• Remove listeners for req body - the request body is fully finalized before it gets to the post handler, so don't need to use event listeners anymore. This simplifies things and makes the tests a lot easier too.
• Unify the fs calls, these are all async now.
• Fix typing.
• Add a couple of git methods for branches and stuff (unused at the moment).
• Alpha sort exports for easy lookup.
• Update all the tests (passing).

To Do

I'd like to revisit this again in the future and tidy up some of the path stuff, i.e. can just use process.cwd() for a lot of the directory stuff. Look at refactoring some of the methods, as a lot of them are quite similar and could probably remove a lot of lines of code here. Shame commonJS doesn't have decorators, as this would be a perfect place to use them.

I forgot to make the helpers executable on this branch... have done so now.

Have also tested this on nodeJS 14.21.3 on a live node... working.
