Lucas Bajolet 4d559e23b7 hcl2: don't warn on excluded post-processor (#12187)
* hcl2template: use && for chaining conditions

For deciding if we need to run an error provisioner block, we checked
using a nested if that we didn't need to avoid running it.

This is unnecessary, and adds a superfluous level of inbrication to the
code, so we chain both conditions with &&.

* hcl2: don't warn on excluded post-processor

When a post-processor is excluded through the -except command-line
argument for packer build, we used to print a warning on HCL2 templates
if this except statement did not match a build.

However, since we can use the except option to avoid running
post-processors, we should account for this as well when printing out a
warning that there were no matches.

This commit adds this counter to the except checks for the
post-processors as well.

Lucas Bajolet bb2384c56a command/validate: add option to eval datasources
When packer validate is invoked, it does not try to evaluate the
datasources before attempting to decide if the template is valid.

In many cases, this works, but sometimes it will fail as the value is
unknown by the validation code.

Since the validation code for all the elements of a Packer template is
left to be implemented by plugins, we cannot rely on checking for
unknown values everywhere, especially since the unknown references are
replaced automatically by a value of the right type for the
configuration expected.

So, in order for such configurations to be validable, we add an extra
option to packer validate, that will let users evaluate the datasources
from a template.

Lucas Bajolet c0e7e7bd3c hcl2: report error on build without sources
When a template describes a build block without a source reference, the
build should be considered invalid as we won't have a CoreBuild produced
as a result of the need to have both.

In current versions of Packer, this will produce an error message
hinting that nothing will happen because of the lack of either build or
source block.

This commit takes the defined block, and points out to it as missing a
source block as being the reason why nothing is happening, making it
clearer what is required for an HCL2 build to be processed.

Lucas Bajolet 61c56e161c hcl2: add example for undefined variable set warn
When a variable is set in a pkrvars file, but isn't defined, an error
message is output, but does not deliver an example of what is expected
by Packer in order to complete a build.

To remedy that, we improve the error message by giving an example of
variable block to include in the build template.

Lucas Bajolet e94b8766cb build: exit immediately if no builds and diags
When a template with some builds to run ends its GetBuilds with an
error, and no builds produced, we can exit immediately without printing
more errors.

Lucas Bajolet a298617ecb command/build: warn and exit when nothing to build
When a `packer build' is run on a config that does not define anything
to be built, the process would run normally, and only state that no
artifacts were produced after builds were run successfully.

This is misleading as we reach the end of the command without having a
proper warning that nothing was even attempted to be built.

This commit adds a warning when that happens, and leaves immediately
after.

Adrien Delorme 0362a3ec10 all shells: Pass env vars through a key value store (#11569)
* allowing to set shell env vars from a key/value map.
* tests

This new map will work alongside the `environment_vars` but it allows using a
datasource value seamlessly. At validation, and because `environment_vars` was
an array of strings containing `KEY=value`, using datsources would not work,
because these values are not known yet and would evaluate to `<unknown>`. With
this, the value and the key can be unknown and will validate correctly for
datasources.

Adrien DelormeandWilken Rivera e03ad29ca0 Sanitize var code (#11566)
* evaluateLocalVariables: modify code for readability and some (not benchmarked) perfs

* Make default input variable type the DynamicPseudoType

This should be the default, and avoids a panic. This type can represent situations where a type is not yet known. Its meaning is undefined in cty.

* do not take Empty types from default value

* Update types.variables.go

Adrien Delorme 9d0193ac14 add possibility to use variables everywhere in post-processor blocks (#11094)
feature + tests.

Including in:
* name
* only
* except
* keep_input_artifact

Example file:

```hcl
source "null" "example1" {
  communicator = "none"
}

source "null" "example2" {
  communicator = "none"
}

locals {
  except = "null.example1"
}

variable "only" {
  default = "null.example1"
}

build {
  sources = ["source.null.example1", "source.null.example2"]
  post-processor "shell-local" {
    except = [local.except]
    inline = ["echo first post-processor"]
  }

  post-processor "shell-local" {
    only   = [var.only]
    inline = ["echo second post-processor"]
  }
}
```
Ouput:
```shell-session
$ packer build foo.pkr.hcl
null.example1: output will be in this color.
null.example2: output will be in this color.

==> null.example1: Running post-processor:  (type shell-local)
==> null.example2: Running post-processor:  (type shell-local)
==> null.example2 (shell-local): Running local shell script: /var/folders/3k/2gb5ct4s7cncr52_jh2kz6cw0000gq/T/packer-shell201696062
==> null.example1 (shell-local): Running local shell script: /var/folders/3k/2gb5ct4s7cncr52_jh2kz6cw0000gq/T/packer-shell494781572
    null.example1 (shell-local): second post-processor
Build 'null.example1' finished after 61 milliseconds 432 microseconds.
    null.example2 (shell-local): first post-processor
Build 'null.example2' finished after 111 milliseconds 678 microseconds.

==> Wait completed after 111 milliseconds 714 microseconds

Adrien Delorme 77a29fc2f8 Allow to have dynamic blocks in a build block + tests (#10825)
This :
* allows to have a `build.dynamic` block
* add tests
* makes sure to show a correct message when a source was not found
  * display only name of source (instead of a weird map printout) 
  * use a "Did you mean %q" feature where possible 


Because dynamic blocks need all variables to be evaluated and available, I moved parsing of everything that is not a variable to "after" variables are extrapolated. Meaning that dynamic block get expanded in the `init` phase and then only we start interpreting HCL2 content.

After #10819 fix #10657

Adrien Delorme c7b35dd6bc HCL2: add post-processors block to run multiple post-processor after a build (#9638)
added `post-processors` block to run chained post-processors after a build.
Before this, defining multiple `post-processor` blocks after
provisioning steps would run them sequentially, now doing this makes them start
from the build's artifact. To queue post-processors you now have to define them
in a `post-processors` block.

This is a breaking change.
