James Bardin 2d7dc605a0 get communicator errors from a remote.Cmd
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.

James Bardin e6f58f5817 Add upload tests
These are skipped without the SSH_UPLOAD_TEST flag, since they require
connecting to a running ssh server on localhost as the current user, and
one creates a very large file.

Sander van Harmelen 968472a63e Support recreating clients and configuring Chef Vaults (#8577)
Fixes #3605 and adds the functionality suggested in PR #7440.

This PR is using a different appraoch that (IMHO) feels cleaner and (even more important) adds support for Windows at the same time.

communicator/{ssh,winrm}: seed random script paths
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!

Paul Hinze 801aaf1eec communicator/ssh: sort agent after static keyfile
In the SSH client configuration, we had SSH Agent authentication listed
before the static PrivateKey loaded from the `key_file` setting.
Switching the default of the `agent` setting exposed the fact that the
SSH agent overrides the `key_file` during the handshake. By listing the
`key_file` first, we catch the provided key before any query goes out to
the agent.

Adds a key-based authentication SSH test to cover this new behavior. It
fails without the reordering on any machine with an SSH agent running.

Fixes #2614

Sander van Harmelen 41748003c0 Updated the PR according to the review comments
* 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…

Sander van Harmelen c9e9e374bb Adding some abstractions for the communicators
This is needed as preperation for adding WinRM support. There is still
one error in the tests which needs another look, but other than that it
seems like were now ready to start working on the WinRM part…
