local_dev

if you clone the repoi locally and set local_dev = true`in dev.tfvars or use terraform apply -var-file=./dev/tfvars -var local_dev=true the normal build process skips most of the process.

with this flag set you will only get a single file local_dev.pkr.hcl which is a cut down version of the build file for local testing

uses azcli auth rather than service principal
removes most of the remote build settings
removes the shared image gallery upload

so that you can run packer build and it should build you an image much more quickly than usual - so yoiu can test your customisation
