* GH-8755 - Adding in support to attach ASG to ELB as independent action
* GH-8755 - Adding in docs
* 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"
security_groups.3505955000: "sg-1e572667" => "sg-1e572667"

* 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

* Update volume_attachment.html.markdown
For #9618, we added the ability to ignore old diffs that were computed
and removed (because the ultimate value ended up being the same). This
ended up breaking computed list/set logic.
The correct behavior, as is evident by how the other "skip" logics work,
is to set `ok = true` so that the remainder of the logic can run which
handles stuff such as computed lists and sets.
There are three equivalent forms for expressing "everyone" (including
anonymous) in IAM policies:
- "Principals": "*"
- "Principals": {"AWS": "*"}
- "Principals": {"*": "*"}
The more-constrained syntax used by our aws_iam_policy_document data
source means that the user can only express the latter two of these
directly. However, when returning IAM policies from the API AWS likes to
normalize to the first form, causing unresolvable diffs.
This fixes#9335 by handling the "everyone" case as a special case,
serializing it in JSON as the "*" shorthand form.
This change does *not* address the normalization of hand-written policies
containing such elements. A similar change would need to be made in
the external package github.com/jen20/awspolicyequivalence in order to
avoid the issue for hand-written policies.
