Only run terraform pipeline for changes to terraform files

[thekaveman]

E.g. under triggers:

  # only run for changes to Terraform files
  paths:
    include:
      - terraform/*

Wait we already have this filter?

That only applies to the trigger section which covers branches and tags. (In Azure docs, this section is referred to as CI triggers.)

At the same level as trigger, you can define a pr section which will need its own path filter section. (Azure docs call this PR triggers.) If you omit the pr section, it is treated the same as if you defined:

pr:
  branches:
    include:
    - '*'

which does not have a path filter.

This doesn't seem like a problem we need to address right now.
