update terraform to use hash as comment per recommended guidelines

[verbanicm]

Hashicorp documentation references using hash (#) as the default comment and is generally preferred to the long block comment style.

Look like a couple of unnecessary changes accidentally got included. Could you back those out? (or I can do it later when I have a little more time)

Reverted those lines, auto formatter ftw!
