* [builder/azure-arm] Use VM/build location for image locationThe builder was using the location of the containing resource group asthe image location, but the API call can only create images in the samelocation as the source VM that is being captured.
* mapstructure-to-hcl2: when we see a map generate an attribute spec and not a block spec
this will alow to do
tags = {
key = "value"
}
instead of
tags {
key = "value"
}
This will also enable using variables directly for those tags
* generate code
* update tests
