This adds the new `required_plugins` block to be nested under the packer block.
Example:
```hcl
packer {
required_plugins {
aws = {
version = ">= 2.7.0"
source = "azr/aws"
}
azure = ">= 2.7.0"
}
}
```
For example on darwin_amd64 Packer will install those under :
* "${PACKER_HOME_DIR}/plugin/github.com/azr/amazon/packer-plugin-amazon_2.7.0_x5.0_darwin_amd64"
* "${PACKER_HOME_DIR}/plugin/github.com/hashicorp/azure/packer-plugin-azure_2.7.0_x5.0_darwin_amd64_x5"
+ docs
+ tests
* update consul and vault dependencies
* update triton sign call accorting to https://github.com/joyent/triton-go/pull/135
* Delete readme.md
* put back github.com/mitchellh/reflectwalk to v1.0.0 and explain why
* fix/fixer_pp_docker_tag_tags.go: simplify deduplication loop and keep seen/stable order
on windows: if the term is resized when ReadString is being called and no one is reading form ws, we get a panic: send on closed channel.
It could make sense to poll getconsolescreenbufferinfo calls instead of this:
something started from the sigwinch() func
on unix: same story, sigwinch was listened upon by default but if the
signals (chan sends) were not handled, this could cause a crash
fix#7434
* removed packer.Cache and references since packer.Cache is never used except in the download step. The download step now uses the new func packer.CachePath(targetPath) for this, the behavior is the same.
* removed download code from packer that was reimplemented into the go-getter library: progress bar, http download restart, checksuming from file, skip already downloaded files, symlinking, make a download cancellable by context.
* on windows if packer is running without symlinking rights and we are getting a local file, the file will be copied instead to avoid errors.
* added unit tests for step_download that are now CI tested on windows, mac & linux.
* files are now downloaded under cache dir `sha1(filename + "?checksum=" + checksum) + file_extension`
* since the output dir is based on the source url and the checksum, when the checksum fails, the file is auto deleted.
* a download file is protected and locked by a file lock,
* updated docs
* updated go modules and vendors
