TACOS reporting false plans

[mwarkentin]

Steps to Reproduce

• Disk size was changed manually (bin/resize-disks most likely)
• Make a terraform change to increase the disk beyond the current value

Expected Result

TACOS fetches proper "current" values for plan rendering

Actual Result

Local run:

# google_compute_disk.data["2-2"] will be updated in-place
  ~ resource "google_compute_disk" "data" {
        id                        = "projects/internal-sentry/zones/us-central1-b/disks/snuba-spans-mz-2-2-data"
        name                      = "snuba-spans-mz-2-2-data"
      ~ size                      = 22000 -> 26000
        # (13 unchanged attributes hidden)

TACOS run:

  # google_compute_disk.data["2-2"] will be updated in-place
  ~ resource "google_compute_disk" "data" {
        id                        = "projects/internal-sentry/zones/us-central1-b/disks/snuba-spans-mz-2-2-data"
        name                      = "snuba-spans-mz-2-2-data"
      ~ size                      = 20000 -> 26000
        # (13 unchanged attributes hidden)
    }
