Some AMIs have a RootDeviceName like "/dev/sda1" that does not appear as a
DeviceName in the BlockDeviceMapping list (which will instead have
something like "/dev/sda")
While this seems like it breaks an invariant of AMIs, it ends up working
on the AWS side, and AMIs like this are common enough that we need to
special case it so Terraform does the right thing.
Our heuristic is: if the RootDeviceName does not appear in the
BlockDeviceMapping, assume that the DeviceName of the first
BlockDeviceMapping entry serves as the root device.
fixes#2224
I was getting an error about a missing 'name' parameter when using the snippet from the docs that referenced a path value. Looking into the source, I found it was actually supposed to be name for the atlas provider.
* adds `bastion_*` fields to `connection` which add configuration for a
bastion host
* if `bastion_host` is set, connect to that host first, then jump
through it to make the SSH connection to `host`
* enables SSH Agent forwarding by default
This changes SSH Agent utilization from opt-in to opt-out, bringing
Terraform in line with the behavior of Packer and the `ssh` command
itself.
But skip SSH agent connections if the SSH_AUTH_SOCK env var doesn't exist,
whcih means there's no agent to connect to.

The Exists function can run in a context where the contents of the
template have changed, but it uses the old set of variables from the
state. This means that when the set of variables changes, rendering will
fail in Exists. This was returning an error, but really it just needs to
be treated as a scenario where the template needs re-rendering.
fixes#2344 and possibly a few other template issues floating around
