docs: Clearly document built in template variables

[rickard-von-essen]

The docs doesn't clearly enumerate the builtin template variables such as {{ .Name }} (and possibly some more).

It would be grand to have this documentation. Especially, as I am attempting to find a suitable replacement for the previous template variable .Provider.

This would be very useful indeed. Any taker?

Does the templating engine also support conditional logic as shown here? If so, that would also be good to document. (Or at least reference that page, possibly with a few packer-specific examples.)

@Mr-Nietzsche I'm pretty sure to unsubscribe from a github issue you have to do so via the unsubscribe button in the issue UI.

@evancox10 Yes, you can use that conditional logic and it's a good idea to document it somewhere. I know the puppet docs have some examples because the defaults contain some of this kind of logic: https://www.packer.io/docs/provisioners/puppet-masterless.html but we could probably link these docs in our general discussion of how the template engine works.

Why has this been closed? The {{ .Name }} built-in variable is still not mentioned in the docs.

[rickard-von-essen]

@noshky this isn't closed..?
