HCL2 Packer configuration template files.
Related to: #9174
* command/fmt: Add check flag
Packer's fmt command now supports a check flag that will output the name
of any file that would be changed by the HCL2 formatting engine. The
check flag is mutually exclusive with the write flag and will only check
if formatting is needed.
The update write flag will now overwrite the source files with the newly
formatted HCL2 source unless the `-write=false` or `-check` is passed at
the command line.
* Returns a diagnostic error if Format is unable to show a diff - equivalent to `terraform fmt`
* Updates testing to run against #Format and not the private methods of the HCL2Formatter; fixes ShowDiff test failure on Windows
* Updates comments for exported functions
* Add docs for fmt command
* hcl2template/addrs.ParseRef will parse a reference and tell for example if we
are referring to a variable and its name, for now it can only do that and in
the future it improved when we need to most of it is from the TF code. This
is used to tell wether a variable vas referenced in a variable validation
condition; for now.
* Added Validations blocks to the hcl2 Variable struct and code to
parse/validate that.
* add the possibility to set the packer.required_version field; to make sure the template file works with that version of Packer
* add tests
* add documentation on packer.required_version
Example:
packer {
required_version = ">= 1.2.0, < 2.0.0"
}
* refactor aws get secrets function out to reuse it else where
* add aws_secretsmanager func and docs for HCL2
* fix GetSecret: allow to pick secret version
