Match the tested behavior, and that of the ssh implementation, where the
communicator automatically connects when starting a command.
Remove unused import from legacy dependency handling.
The error from a remote command is not exported, and only exposed via
the Run method. Otherwise the Run method works exactly like the
runCommand function being removed.
The remote.Cmd struct could not convey any transport related error to
the caller, meaning that interrupted commands would show that they
succeeded.
Change Cmd.SetExited to accept an exit status, as well as an error to
store for the caller. Make the status and error fields internal,
require serialized access through the getter methods.
Users of remote.Cmd should not check both Cmd.Err() and Cmd.ExitStatus()
until after Wait returns.
Require communicators to call Cmd.Init before executing the command.
This will indicate incorrect usage of the remote.Cmd by causing a panic
in SetExitStatus.
It appears that the cacert option for the winrm provisioner was
not getting passed correctly to the winrm package. Log output
showed that CACert was false regardless of configuration.
While the validation of the connector looked for cacert, the winrm
communicator looked for ca_cert.
This changeset performs the following:
- Updates `masterzen/winrm` vendor to include change from (https://github.com/masterzen/winrm/pull/73)
- Updates `dylanmei/winrmtest` vendor to include change from (https://github.com/dylanmei/winrmtest/pull/4)
- Updates `packer-community/winrmcp` vendor to include the removal of the `masterzen/winrm/winrm` sub-class as a result of the `winrm` CLI tool being removed from the `masterzen/winrm` repository.
- Changes `communicator/winrm/communicator.go` to conform to the new ABI in the `masterzen/winrm` library.
This should completely remove any LGPL licensed dependencies inside of the Terraform project.

```
Without a seed, the "random" script path locations for the remote-exec
provisioner were actually deterministic!
Every rand.Int31() would return the same pseudorandom chain starting w/
the numbers: 1298498081, 2019727887, 1427131847, 939984059, ...
So here we properly seed the communicators so the script paths are
actually random, and multiple runs on a single remote host have much
less chance of clobbering each other.
Fixes#4186
Kudos to @DustinChaloupka for the correct hunch leading to this fix!
As the command completes, the winrm.Command does not wait for its copy of
the remote.Command streams to report itself completed.
This adds an additional sync.WaitGroup to ensure that copy is finished up
before moving on, solving the data race.
Fixes the following data race:
```

==================
```
I added a debug log line in the last commit, only to find out it’s now
logging the same info twice. So removed the double entry and tweaked
the existing once.
Pretty nice test coverage this way, covering all WinRM actions/logic by
using the winrmtest package. I had to extend/update/fix that package a
little here and there, but it now serves a nice purpose for testing
WinRM stuff…
* We now return an error when you set the script_path to
C:\Windows\Temp explaining this is currently not supported
* The fix in PR #1588 is converted to the updated setup in this PR
including the unit tests
Last thing to do is add a few tests for the WinRM communicator…
