* add sshkey.Generate function that returns an sshkey.Pair to be used with openssh.
* add cmd/ssh-keygen/main.go for testing purposes
* add a test calling ssh.ParsePrivateKey & ssh.ParseAuthorizedKey (which is very
similar to what openssh would do to read a keypair)
The wrapping of the keys should be handled by crypto/x509.MarshalPKCS8PrivateKey
& x/crypto/ssh.NewPublicKey which does not work for ed25519 and dsa.
x509.MarshalPKCS8PrivateKey marshals ed25519 keys but the keys did not work with openssh.
x509.MarshalPKCS8PrivateKey does not handle dsa keys.
So I had to 'wrap' those manually by reading the code of the openssh package.
Note that ssh.NewPublicKey works with any keytype. I should probably do a PR to ssh to have a NewPrivateKey & Marshalling funcs
* Implement Stringer inteface for multistep.StepAction
* scaleway: add pre validate step (check image and snapshot names)
Before, it was possible to create multiple images with the same name,
leading to a confusing and wasteful situation (same for snapshots).
Now, we perform the same kind of checks done by the AWS EC2 builder,
and refuse to proceed if there is an existing image with the same name
(same for snapshots).
As usual, invoking `packer build -force` will bypass the checks.
Closes#9839.
The initialization of packer core in JSON also validates that `null` variables were set, except in the case of `packer validate --syntax-only` , but after the refactor to allow to have all commands work with HCL2 and JSON this subtlety was lost.
This refactors the initialisation of the core in order to allow to have `packer validate --syntax-only` not error in case a variable is not set. Since these calls are refactored this works for HCL2 too.
fix#9478
* add kex algorithm option to ssh config
* regenerate code
* This commit fixes old vmware acceptance tests that have not been run in some time. It does this in two parts:
1) It modifies the minimal vmware build configuration to use a custom kex algorithm, which enables the ssh connection to succeed.
2) It modifies logic in reading and defaulting hardware config values, which was crashing.
3) It adds a new acceptance test with a preseed file to test loading from an http directory.
* 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
