Adrien Delorme 5ef1893b00 fix crash when build.sources is set to an invalid name 
the `build` body doesn't have any labels and we were trying to display those.
I also added a test.

build using HCL2 (#8423) 
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

close #1768


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 {
        Name = "packer-solr-something"
        stack-name = "DevOps Tools"
    }
    
    communicator = "ssh"
    ssh_pty = true
    ssh_username = "ec2-user"
    associate_public_ip_address = true
}

Adrien Delorme bf3d9841c6 Force durations to be passed a strings 
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".

Package hcl2template defines code to parse hcl2 template files correctly.

In order to configure a packer builder,provisioner,communicator and post
processor.

Checkout the files in testdata/complete/ to see what a packer config could
look like.
