* 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

to allow just reading the config and to not start anything. This will allow to later on run `validate --syntax-only`.
Note that none of the builder/provisioner/post-processor config will be read but simply ignored. HCL2 still needs the body to be properly formatted and it should detect most syntax errors.
* 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
