* Update validate command to use FixConfig for checking against known
fixers
* Update validation command flag docs
* Add ConfigFixer method to PackerHandler Interface
* Implement ConfigFixer interface in PackerConfig
* Remove all stdout messaging (i.e calls to c.Ui.Say) in the validate
command. The command will only display hcl.Diagnotic messaging when there is an error or warning.

* refactor so that json and hcl2 templates are both prepared in the same place in the build call, to make code easier to reason about. Remove overly verbose error output which isn't useful in vast majority of cases
* fix tests
* check err msg
* hcl2template.PackerConfig.GetBuilds: raise a diagnostic in case the packer core build perpare call errors

This function can be used to check if a Provisioner has been marked for testing within the ACC_TEST_PROVISIONERS environment variable.
While testing I found that the shell acceptance test were also running when trying to run powershell tests.
Before change
```
⇶ ACC_TEST_BUILDERS=amazon-ebs ACC_TEST_PROVISIONERS=powershell go test -v ./provisioner/shell/... -timeout=1h
=== RUN
TestShellProvisioner/testing_amazon-ebs_builder_against_shell_provisioner
2020/04/06 15:18:12 ui: amazon-ebs: output will be in this color.

* Add golangci-lint as linting tool
* Disable failing staticchecks to start; GitHub issue to handle coming soon
* Run `goimports -w` to repair all source files that have improperly
formatted imports
* makefile: Add ci-lint target to run on travis
This change adds a new make target for running golangci-lint on newly
added Go files only. This target is expected to run during Packer ci builds.
* .github/contributing: Add code linting instructions
* travis: Update job configuration to run parallel builds
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
source_ami_filter {
filters {
virtualization-type = "hvm"
name = "amzn-ami-hvm-????.??.?.????????-x86_64-gp2"
root-device-type = "ebs"
}
most_recent = true
owners = ["amazon"]
}
launch_block_device_mappings {
device_name = "/dev/xvda"
volume_size = 20
volume_type = "gp2"
delete_on_termination = "true"
}
launch_block_device_mappings {
device_name = "/dev/xvdf"
volume_size = 500
volume_type = "gp2"
delete_on_termination = true
encrypted = true
}
ami_regions = ["eu-central-1"]
run_tags {

stack-name = "DevOps Tools"

```
It is simply the best/simplest solution and trying to prevent users from passing and integer here would be like opening a can of worms. Because:
* we cannot make mapstructure validate our duration string ( with an UnmarshalJSON func etc.)
* we cannot make mapstructure spit a string instead of a duration and packer will decode-encode-decode config.
* the hcl2 generated code asks for a string, so this will be enforced by default.
Before this commit it was possible to set a duration using an integer or a float. Go's time.Duration is an int64 internally an mapstructure will take advantage of this and load the number as a int64 but `1` means one ns which is unexpected/confusing. To avoid confusion and enforce readability this forces users to pass a string with a unit for a duration; ex "56s".
Support for both local and remote TCP port tunneling. Includes updated
docs and tests.
Does not implement dynamic port forwarding (SSH's built-in SOCKS)
(uncertain difficulty) nor unix socket (potentially easy).
* add missing `temporary_key_pair_name` field for alicloud
* add missing description to `vpc_filter` for aws
* add missing ssh communicator fields for aws
* add links for aws
* update vmware-vmx docs
* manually describe AMI Configuration section for ebsvolume
* display missing required ami_name field for aws
* add missing fields for docker
* add missing fields for openstack
The 'ssh.KeyPairFromPrivateKey()' function in the 'ssh' helper
library was not honoring the value of the 'Comment' field in the
'FromPrivateKeyConfig' struct. This commit fixes the issue, and
updates unit tests to catch the issue if it happens again.
* I had to contextualise Communicator.Start and RemoteCmd.StartWithUi
NOTE: Communicator.Start starts a RemoteCmd but RemoteCmd.StartWithUi will run the cmd and wait for a return, so I renamed StartWithUi to RunWithUi so that the intent is clearer.
Ideally in the future RunWithUi will be named back to StartWithUi and the exit status or wait funcs of the command will allow to wait for a return. If you do so please read carrefully https://golang.org/pkg/os/exec/#Cmd.Stdout to avoid a deadlock
* cmd.ExitStatus to cmd.ExitStatus() is now blocking to avoid race conditions
* also had to simplify StartWithUi
* 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
Per code review feedback, the Go template library supports
encoding variables in URL query format. Instead of exposing
two different public key formats (unmodified string and a
URL encoded string), just have the user apply the 'urlquery'
modifier to their template.
