Before this, the Terraform Puppet provisioner would error out in a
confusing way if the type attribute in a connection block was not given.
Apparently an omitted type leads to type having a value "" which must be
then assumed to mean "ssh".
Fixes#23004
Due to an incorrect slice allocation, the environment variable list was created with an empty string
element for each real element added.
It appears that this was silently ignored on Unix, but caused the following environment settings
to be ignored altogether on Windows.
Add a test to remote-exec to make sure the proper timeout is honored
during apply.
TODO: we need some test helpers for provisioners, so they can all be
verified.
The timeout for a provisioner is expected to only apply to the initial
connection. Keep the context for the communicator.Retry separate from
the global cancellation context.

Combine the ExitStatus and Err values from remote.Cmd into an error
returned by Wait, better matching the behavior of the os/exec package.
Non-zero exit codes are returned from Wait as a remote.ExitError.
Communicator related errors are returned directly.
Clean up all the error handling in the provisioners using a
communicator. Also remove the extra copyOutput synchronization that was
copied from package to package.
Use the new ExitStatus method, and also check the cmd.Err() method for
errors.
Remove leaks from the output goroutines in both provisioners by
deferring their cleanup, and returning early on all error conditions.
The timeout for the remote command was taken from the wrong config
field, and the connection timeout was being used which is 5 min. Any
remote command taking more than 5 min would be terminated by
disconnecting the communicator. Remove the timeout from the context, and
rely on the global timeout provided by terraform.
There was no way to get the error from the communicator previously, so
the broken connection was silently ignored and the provisioner returned
successfully. Now we can use the new cmd.Err() method to retrieve any
errors encountered during execution.
provisioner. Also fixes an issue where channels and URLs are
not honored in the initial package install.

This new argument allows overriding of the working directory of the child process, with the default still being the working directory of Terraform itself.
There no reason to retry around the execution of remote scripts. We've
already established a connection, so the only that could happen here is
to continually retry uploading or executing a script that can't succeed.
This also simplifies the streaming output from the command, which
doesn't need such explicit synchronization. Closing the output pipes is
sufficient to stop the copyOutput functions, and they don't close around
any values that are accessed again after the command executes.
