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.
Create-before-destroy dependencies are automatically ordered correctly
by terraform. Remove the old notice about requiring all dependencies to
have the same setting for create_before_destroy.
During a full destroy when outputs are removed, the
NodeDestroyableOutput was preventing it's sibling output from being
destroyed. Prune the output node if it only has its destroy node as a
dependent.
The destroy output test is simply run a second time with no state, which
would cause the output interpolation to fail if it remained in the
graph.
This was already added to triton-go and is now making its way to
the manta backend

If an existing resources is scaled back to 0, locals and outputs will
still have a multi-variable reference to evaluate, which should return
an empty list. Due to how the resource is removed, the resource will
still exist in the state but with no primary instance, which needs to be
ignored in the instance count.
Most of the time an ssh authentication failure would be non-recoverable,
but some host images can start the ssh service before it is properly
configured, or before user authentication data is available.
Log ssh authentication errors and allow the provisioner to retry until
the connection timeout.
Added some more context to GetOkExists, moved Computed to NewValueKnown
to accommodate some changes that will be coming up in HCL2 that may make
"Computed" less intuitive of a function name, and updated the docs for
NewValueKnown as well.
