* I had to contextualise Communicator.Start and RemoteCmd.StartWithUi
NOTE: Communicator.Start starts a RemoteCmd but RemoteCmd.StartWithUi will run the cmd and wait for a return, so I renamed StartWithUi to RunWithUi so that the intent is clearer.
Ideally in the future RunWithUi will be named back to StartWithUi and the exit status or wait funcs of the command will allow to wait for a return. If you do so please read carrefully https://golang.org/pkg/os/exec/#Cmd.Stdout to avoid a deadlock
* cmd.ExitStatus to cmd.ExitStatus() is now blocking to avoid race conditions
* also had to simplify StartWithUi
* 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
Per code review feedback, the Go template library supports
encoding variables in URL query format. Instead of exposing
two different public key formats (unmodified string and a
URL encoded string), just have the user apply the 'urlquery'
modifier to their template.
The SSH public key (in authorized_keys format) can be retreived in
the build template by specifying '{{ .SSHPublicKey }}'. The key is
URL encoded to escape spaces.
The default behavior of the various builders that create SSH key
pairs appears to be to add a trailing new line. This will be the
default behavior, but at least it can be customized if desired.
As we know the exact versions that used the old `sataportcount` option, it's safe to assume we want to use the newer `portcount` option for everything else.
Reversed the option check and use the `portcount` option by default. Prevents needing to update this for future major versions of VirtualBox.
this regroups the calls of tmp func calls into one package.
the tmp pkg allows to store tmp files under a common directory for easier managment

Let's cache the scancodes and flush them at the end. Also make sure to
send only as many as the driver can send correctly. It's important here
to chunk the scancodes correctly, so that we don't accidentally split them
over successive calls to the driver
Run now takes a context as well as a statebag. We'll assign the context
to the blank identifier to prevent namespace collisions. We'll let the
step authors opt-in to using the context.
`find . -iname "step_*.go" -exec gsed -i'' 's/func \(.*\)Run(/func \1Run(_ context.Context, /' {} \;`
[A recent breaking change upstream in Golang's crypto
library](e4e2799dd7)
has broken SSH connectivity for a few builders:
```

```
Specifying HostKeyCallback as insecure should make things work again
and would make sense for packer's use case.
If using a builder that has an http server set up for file transfer,
expose the connection info to the shell provisioner through the environment
variable PACKER_HTTP_ADDR.
Closes#2869
