James Bardin 197f6cab79 Cannot store multiple types in atomic.Value
Storing error values to atomic.Value may fail if they have different
dynamic types. Wrap error value in a consistent struct type to avoid
panics.

Make sure we return a nil error on success

Peter McAtominey d2047d714e provisioner/remote-exec: fail on first inline script with bad exit code (#11155)
The provisioner collected all inline commands into a single script which meant
only the exit code of the last command was actually checked for an error.

communicator/ssh: don't share rand object to guarantee unique values
Fixes #10463

I'm really surprised this flew under the radar for years...

By having unique PRNGs, the SSH communicator could and would
generate identical ScriptPaths and two provisioners running in parallel
could overwrite each other and execute the same script. This would
happen because they're both seeded by the current time which could
potentially be identical if done in parallel...

Instead, we share the rand now so that the sequence is guaranteed
unique. As an extra measure of robustness, we also multiple by the PID
so that we're also protected against two processes at the same time.

Paul Hinze 579680cebc provisioner/remote-exec: Move script cleanup after command wait
The script cleanup step added in #5577 was positioned before the
`cmd.Wait()` call to ensure the command completes. This was causing
non-deterministic failures, especially for longer running scripts.

Fixes #5699
Fixes #5737

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…
