Healthcheck Implementation

[ColdHeat]

I believe our healthcheck implemtnation is currently lacking so just writing some notes on improving it.

I believe ctfcli should treat a solve script as a kind of template. Possibly a Jinja template and populate specific variables and then run the script.

For example we could have something like:

#!/usr/bin/python3
connect("{{ host }}", {{ port }})

ctfcli will render this to a temporary file and then execute it.

Likely, if the healthcheck file ends in .jinja

We can render it to the same folder with the extension removed and then execute the script.

So for example:

healthcheck: solve.py.jinja

This points to a solution script expecting jinja variables. It gets templated by ctfcli, then written to solve.py and then executed via subprocess.

Although likely it might just make more sense to just keep it reading as argument variables...
