developer friendly gate hook scripts

[alanmeadows]

Problem description (if applicable)
The airshipctl end-to-end test is currently launched by Zuul infrastructure. We need to ensure these same gates can act as developer friendly scripts to launch a virtualized airshipctl environment locally.

Proposed change
While the ansible gate playbooks can be launched by hand with a series of flags and environmental settings, we need to make this more approachable to new developers. This issue proposes a series of simple idempotent scripts that developers can run which will exercise the gate locally, without Zuul infrastructure, e.g.

tools/gate/01_create_iso.sh
tools/gate/02_launch_ephemeral_node.sh
...

Potential impacts
None

We have decided that we will use bash for that, correct? because right now there is some work going on around ansible roles instead of bash

[alanmeadows]

I think the point here is that these simple bash scripts could simply call the ansible roles that are being created. It provides a simple way for developers unfamiliar with ansible, the right environment variables, flags, and so on to set to be able to use those roles.
