installer: update tf-fmt to use latest tf version and mark it optional

[abhinavdahiya]

Installer 1 is in progress to move to terraform version 0.12, which has breaking changes for formatting.
To add to that, upi terraform templates will be moved over to 0.12 at a later stage.

Therefore marking this optional for the time being until we have moved entire code base to 0.12.
