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"

* 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
In order to allow Packer to connect to Private Triton installations
we now expose `insecure_skip_tls_verify` which, if set to true, will
allow the user to make requests to Triton installations that use a
certificate not signed by a trusted root CA
Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
A bug was reported to Joyent, that sometimes packer UI reports that an image was created but it wasn't actually available in Triton for use. We believe that there was a bug uploading that image to Manta but that the metadata of the image was already populated and thus packer was reporting success as it was just checking for the metadata presence
This PR changes Packer to wait for the state of the image to be `active` to make sure that it has fully uploaded and is ready for use

I got the following output from packer:

triton output will be in this color.

I can verify from the triton cli tools that the id `7b5981c4` (from the packer output) is indeed the correct ID

This brings packer into the same version of triton-go as that in Terraform, where we rewrote the package from a library with everything in 1 place to individual packages
I was able to successfully provision a machine on triton using this new change, you can find the output in the attached gist
https://gist.github.com/stack72/a64d745459107c5a16bcb156965597ce
This commit substitutes the now-deprecated gosdc library for the newer
triton-go library. This is transparent from a user perspective, except
for the fact that key material can now be ommitted and requests can be
signed with an SSH agent. This allows for both encrypted keys and ECDSA
keys to be used.
In addition, a fix is made to not pass in an empty array of networks if
none are specified in configuration, thus honouring the API default of
putting instances with no explicit networks specified on the Joyent
public and internal shared networks.
* Fixed minor lint error.
* Added documentation for this builder in `triton.html.md`.
* Added (and updated) the needed Joyent Triton Cloud API Go libraries
to `vendor.json`.
This is a builder for Joyent's Triton system. It was originally at
jen20/packer-builder-triton, and subsequently at
joyent/packer-builder-triton on GitHub. The following commit vendors the
dependencies.
