* 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.
HCL2 Configs

⇶ packer validate docker_centos_shell_provisioner.pkr.hcl

* Deprecated configuration key: 'iso_checksum_type'. Please call `packer fix`
against your template to update your template to be compatable with the current
version of Packer. Visit https://www.packer.io/docs/commands/fix/ for more
detail.
Warning: Fixable configuration found.
You may need to run `packer fix` to get your build to run correctly.
