Fixes#9840
The new apply graph wasn't properly nesting provisioners. This resulted
in reading the provisioners being nil on apply in the shadow graph which
caused the crash in the above issue.
The actual cause of this is that the new graphs we're moving towards do
not have any "flattening" (they are flat to begin with): all modules are
in the root graph from the beginning of construction versus building a
number of different graphs and flattening them. The transform that adds
the provisioners wasn't modified to handle already-flat graphs and so
was only adding provisioners to the root module, not children.
The change modifies the `MissingProvisionerTransformer` (primarily) to
support already-flat graphs and add provisioners for all module levels.
Tests are there to cover this as well.
**NOTE:** This PR focuses on fixing that specific issue. I'm going to follow up
this PR with another PR that is more focused on being robust against
crashing (more nil checks, recover() for shadow graph, etc.). In the
interest of focus and keeping a PR reviewable this focuses only on the
issue itself.

* GH-8755 - Adjusting attribute name and responding to other PR feedback
In #8502 it was requested that we add support for the EnableSNI
parameter of Route53's health checks; this enables customers to
manually specify whether or not the health check will use SNI when
communicating with the endpoint.
The customer originally requested we default to `false`. While
implementing the issue, I discovered that when creating health
checks with a Type set to HTTP, Amazon's default value for EnableSNI
is `false`. However, when creating health checks with a Type set to
HTTPS, Amazon's default value is `true`. So rather than setting a
default value, I made the attribute computed.

When the ALB was ForceNew, the ARN changed. The test has been updated to include a check to make sure that the ARNs are the same after the update
After this change, it looks as follows:
```
~ aws_alb.alb_test

security_groups.1631253634: "" => "sg-3256274b"

* provider/aws: Provide the option to skip_destroy on
aws_volume_attachment
When you want to attach and detach pre-existing EBS volumes to an
instance, we would do that as follows:
```
resource "aws_instance" "web" {
ami = "ami-21f78e11"
availability_zone = "us-west-2a"
instance_type = "t1.micro"
tags {
Name = "HelloWorld"
}
}
data "aws_ebs_volume" "ebs_volume" {
filter {
name = "size"
values = ["${aws_ebs_volume.example.size}"]
}
filter {
name = "availability-zone"
values = ["${aws_ebs_volume.example.availability_zone}"]
}
filter {
name = "tag:Name"
values = ["TestVolume"]
}
}
resource "aws_volume_attachment" "ebs_att" {
device_name = "/dev/sdh"
volume_id = "${data.aws_ebs_volume.ebs_volume.id}"
instance_id = "${aws_instance.web.id}"
skip_destroy = true
}
```
The issue here is that when we run a terraform destroy command, the volume tries to get detached from a running instance and goes into a non-responsive state. We would have to force_destroy the volume at that point and risk losing any data on it.
This PR introduces the idea of `skip_destroy` on a volume attachment. tl;dr:
We want the volume to be detached from the instane when the instance itself has been destroyed. This way the normal shut procedures will happen and protect the disk for attachment to another instance
