Refactor step_export and the driver interface to move the ovftool call
into the vmware driver. This refactor allows us to add meaningful tests
to step_export, which I have also added here.
withouth this fix we would have had to do
```hcl
temporary_iam_instance_profile_policy_document {
statement {
action = ["*"]
effect = "Allow"
resource = ["*"]
}
version = "2012-10-17"
}
```
instead of the same document but with capitalised fields
hcl2_upgrade transforms a JSON build-file in a HCL2 build-file.
This starts a validated Packer core and from that core we generate an HCL 'block' per plugin/configuration. So for a builder, a provisioner, a post-processor or a variable. The contents of each block is just transformed as is and basically all fields are HCL2-ified.
A generated field can be valid in JSON but invalid on HCL2; for example JSON templating (in mapstructure) allows to set arrays of strings - like `x = ["a", "b"]` - with single strings - like `x="a"` -, HCL does not allow this.
Since JSON does not make the distinction between variables and locals, everything will be a variable. So variables that use other variables will not work.
hcl2_upgrade tries to transform go templating interpolation calls to HCL2 calls when possible, leaving the go templating calls like they are in case it cannot.
Work:
* transpiler
* tests
* update hcl v2 library so that output looks great.
* update docs
PutRolePolicy & AddRoleToInstanceProfile are eventually consistent but it is not possible to wait for them to be done here: 0785c2f6fc/builder/amazon/common/step_iam_instance_profile.go (L117-L134) which was causing the `CreateFleet` to fail (100% for me). So for now we retry a bit later. Waiting 5 seconds after the previously linked code also fixed this.

This changes updates the AWS Secrets manager session authentication
logic to support reading the AWS configuration file for default
credentials and region settings, if they are not provided via
environment variables.
* Modify error output a little to remove stutter "error ... : error ...`
