This fix is at a wrong place.

The following block creates the config for allow_caps

plugin "{{ key }}" {
{{ plugin_config(value) }}
}

My quick and dirty fix:
{{ plugin_config(value) | replace('\'', '\"') }}

The major problem is, that jinja2 cannot create HCL at this point.

@Rendanic The primary issue that I was trying to fix was the casing rather than quoting. It was this casing issue that led me to put the change where I did, as that is where the lowercase operation takes place.

I'm not overly familiar with this project and I don't really mind where any potential fix is placed, just wanted to mention there is the second casing issue in addition to the quoting issue (as I mostly lent on using the example to describe the problem, rather than explaining the two different issues explicitly so it would have been easy to miss).

That said, I haven't actually tried your fix yet and it could be that it does avoid the lowercase operation. If so just ignore this comment.

would like some final vetting from someone if possible

I created a PR (#152) with my fix.
