to accept a list of strings (for Amazon builders).
Per this change, `temporary_security_group_source_cidr` in the configuration:
1. Will be renamed to `temporary_security_group_source_cidrs`.
2. Will accept a list of CIDRs.
3. Will have its documentation updated to reflect this change.
4. Will have a fixer attached for newer templates to avail of.
* 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
Previously, if ami_block_device_mappings was set, and you were building
from an existing image, it would get silently ignored, and changing
root_device_name would be ignored. This changes that behaviour, so
if ami_block_device_mappings is specified, it's respected.
