This follows #8232 which added the code to generate the code required to parse
HCL files for each packer component.
All old config files of packer will keep on working the same. Packer takes one
argument. When a directory is passed, all files in the folder with a name
ending with “.pkr.hcl” or “.pkr.json” will be parsed using the HCL2 format.
When a file ending with “.pkr.hcl” or “.pkr.json” is passed it will be parsed
using the HCL2 format. For every other case; the old packer style will be used.
## 1. the hcl2template pkg can create a packer.Build from a set of HCL (v2) files
I had to make the packer.coreBuild (which is our one and only packer.Build ) a public struct with public fields
## 2. Components interfaces get a new ConfigSpec Method to read a file from an HCL file.
This is a breaking change for packer plugins.
a packer component can be a: builder/provisioner/post-processor
each component interface now gets a `ConfigSpec() hcldec.ObjectSpec`
which allows packer to tell what is the layout of the hcl2 config meant
to configure that specific component.
This ObjectSpec is sent through the wire (RPC) and a cty.Value is now
sent through the already existing configuration entrypoints:
Provisioner.Prepare(raws ...interface{}) error
Builder.Prepare(raws ...interface{}) ([]string, error)
PostProcessor.Configure(raws ...interface{}) error

Example hcl files:
```hcl
// file amazon-ebs-kms-key/run.pkr.hcl
build {
sources = [
"source.amazon-ebs.first",
]
provisioner "shell" {
inline = [
"sleep 5"
]
}
post-processor "shell-local" {
inline = [
"sleep 5"
]
}
}
// amazon-ebs-kms-key/source.pkr.hcl
source "amazon-ebs" "first" {
ami_name = "hcl2-test"
region = "us-east-1"
instance_type = "t2.micro"
kms_key_id = "c729958f-c6ba-44cd-ab39-35ab68ce0a6c"
encrypt_boot = true

name = "amzn-ami-hvm-????.??.?.????????-x86_64-gp2"

}
most_recent = true

}
launch_block_device_mappings {

* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
This commit adds a new option, `vmx_remove_ethernet_interfaces`, to both
of the VMWare builders. This is useful when building Vagrant boxes,
since Vagrant now produces output such as:
```
WARNING: The VMX file for this box contains a setting that is
automatically overwritten by Vagrant when started. Vagrant will stop
overwriting this setting in an upcoming release which may pre vent
proper networking setup. Below is the detected VMX setting:
ethernet0.pcislotnumber = "33"
If networking fails to properly configure, it may require this VMX
setting. It can be manually applied via the Vagrantfile:
Vagrant.configure(2) do |config|
config.vm.provider :vmware_fusion do |vmware|
vmware.vmx["ethernet0.pcislotnumber"] = "33"
end
end
```
This can be avoided entirely by removing the ethernet adapters from the
VMX file prior to packaging as a Vagrant box, in which case adapters are
created as expected according to the Vagrantfile specification.
Ensure that all builders include FloppyDirectories in the StepCreateFloppy options.
Changed the way the unit-tests in common/step_create_floppy_test work to use the static test-fixtures directory instead of creating the paths dynamically.
Removed a duplicate line of documentation from parallels-pvm.html.md that occurred during rebasing.
Moved the support for recursive paths from the floppy_files keyword to the new floppy_contents keyword.
Shifted some of the code around to add better logging of what's actually being copied.
Added a couple of unit-tests for the new floppy_contents implementation.
Ensured that all files that were being added were also being included in state.FilesAdded so that the older unit-tests will work.
When debugging a build (or maintaining an existing packer file), teach `packer build -debug` how to step through individual `boot_command`s in order to triage the packer file.
