* 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
Add template option skip_validate_credentials allowing users to skip this validation if they don't want it.
Refactor vmware-iso builder to separate out config so that it matches the vmware-vmx builder and simplifies the builder.go file
arizvisa: Updated icnocop's documentation to include the possible disk adapter types that one can specify.
arizvisa: Tweaked icnocop's support for the `disk_adapter_type` option to the VMWare builder that caused conflicts due to version skew.
icnocop: Updated links to the Virtual Disk Manager User's Guide PDF to open in a new window and also added the Adobe PDF icon
icnocop: Added support for vmware to specify the disk adapter type, ide or scsi (lsilogic or buslogic)
builder/vmware/{iso,vmx}:
Added the specific configuration options that get parsed.
Normalize paths when pulling them from the json template so that they'll work on Windows too.
Added some improved error checking when parsing these options.
Stash the vm's network connection type so that other steps can figure out addressing information
Modified the esx5 driver to support the new addressing logic.
Modified the template in step_create_vmx to include the new options.
builder/vmware/common:
Implemented a parser for vmware's configuration files to the vmware builder.
Modified the driver's interface to include support for resolving both guest/host hw and ip addresses
Implemented a base structure with some methods that implement these features.
Rewrote all ip and mac address dependent code to utilize these new methods.
Removed host_ip and guest_ip due to their logic being moved directly into a
base-structure used by each driver. The code was explicitly checking runtime.GOOS
instead of portably using net.Interfaces() anyways.
Updated driver_mock to support the new addressing methods
