[Suggestion] Remove inlets specific references from the provisioners

At this moment, many provisioners have some specific, hard-coded references to inlets. Like tags or firewall rules.
Referring to this repository: https://github.com/inlets/provision-cloudinit-go, removing those references and making the provisioners more generic, they can be used as a library by others.

## Expected Behaviour
Most provisioners create cloud host with hard-coded inlets references, like tags.

## Current Behaviour
The provisioners can be used by others without creating inlets tags.

## Possible Solution

Pass the inlets references to the provisioners as arguments. I'm aware this can be a tedious task, as there are many provisioners and they all have a target cloud specific implementation.

## Steps to Reproduce (for bugs)

N/A

## Context

Playing around with the provisioners as a library, I've noticed that the cloud hosts are tagged with "inlets"., while I was creating other, non-inlets relared hosts.

## Your Environment

* inlets version `inlets --version`
N/A
* Docker/Kubernetes version `docker version` / `kubectl version`:
N/A
* Operating System and version (e.g. Linux, Windows, MacOS):
