This isn't working locally, but it matches the changes made in https://github.com/terraform-providers/terraform-provider-azurerm/pull/2722 so maybe something freaky is going on and it will only work in CI?
Edit: This only works in CI (well, at least doesn't work locally for *me*) but the same is true in the Azure provider. Most of those rules can be turned back on provided we make the corresponding code changes, but let's bring back `unused` for now. I'll dupe over to tpgb on approval.
Switch to using Go modules.
This migrates our vendor.json to use Go 1.11's modules system, and
replaces the vendor folder with the output of go mod vendor.
The vendored code should remain basically the same; I believe some
tree shaking of packages and support scripts/licenses/READMEs/etc.
happened.
This also fixes Travis and our Makefile to no longer use govendor.
Parallel to https://github.com/terraform-providers/terraform-provider-azurerm/pull/2116
We need to run `gofmt -s` to switch over to the `gofmt` rule, and MM is going to complicate that. Once `1.20.0` is done, I'll run that command on flat MM files & add a `gofmt -s` step to MM generation (goimports does gofmt but doesn't do the s flag for silly reasons).
I'll duplicate this over to tpgb once this PR is merged.
Many of the d.Set calls do not handle the error that comes back. This can lead
to things that appear to be set but are silently failing. This change adds a
flag to the makefile to force a panic if there are unhandled errors.
