Fixes: #10581
When a cluster was originally created, you could not enable snapshotting
on it. An error message like this was found:
```
* aws_elasticache_replication_group.bar: Error updating Elasticache replication group: InvalidParameterCombination: Must specify both SnapshotRetentionLimit and SnapshottingClusterId to turn on snapshots
status code: 400, request id: 98d2ea4e-3fb1-11e7-b077-5967719aeab4
```
There is no guidance from AWS on which is the preferred Cluster in the RG to use for snapshotting. Therefore, I decided to set it to be the first cluster. We can now enable snapshotting
```

During an instance shut-down network interfaces may be detached during the `READ` method of a Terraform run.
This protects the case where a network interface was detached, and is now `nil` at the time of the Terraform run, fixing nil pointer dereferences.
Previously lightsail was limited to `us-east-1` only. This restriction has now been lifted to new regions.

Fixes: #14668
The previous JSON validator that we were using for IAM policy documents wouldn't catch AWS IAM Policy errors.
The supplied policy document would pass our validator, then fail with the following API error:
```
* aws_iam_role_policy.foo: Error putting IAM role policy tf_test_policy_ymw7hbil9w: MalformedPolicyDocument: The policy failed legacy parsing
status code: 400, request id: e7615d90-3c99-11e7-babc-c14e741605bf
```
This happens if the Policy Document doesn't start with the opening JSON bracket, and often happens in the following case:
```
policy = <<EOF
{
"Version": "2012-10-17",
"Statement": [
{
...
}
]
}
EOF
```
Where, when using a HEREDOC, the policy document is indented incorrectly.
The new validation function for the IAM policies verifies that the first character of the supplied policy document is the leading JSON bracket, prior to validating the JSON string.
Test Output:

I was originally calling the wrong API method and only some of the
values were being persisted to state. By changing the API method, we can
now get all of the values and therefore can detech manual drift

When in a `restricted` cloud, we should fall back to the old method of
tagging. Before this change we saw the following:
```

The Terraform execution plan has been generated and is shown below.
Resources are shown in alphabetical order for quick scanning. Green resources
will be created (or destroyed and then created if an existing resource
exists), yellow resources are being changed in-place, and red resources
will be destroyed. Cyan entries are data sources to be read.
Note: You didn't specify an "-out" parameter to save this plan, so when
"apply" is called, Terraform can't guarantee this is what will execute.
~ aws_instance.foo
tags.%: "0" => "1"
tags.foo: "" => "bar"
Plan: 0 to add, 1 to change, 0 to destroy.
```
After this patch, we see the following:
```

doesn't need to do anything.

When we found an update of IPv6 cidr block, we first tried to
disassociate the old cidr block association. This caused errors if there
was none, it threw an error, as we passed an empty associationId:
```

status code: 400, request id: f438f468-9ca4-4000-ba78-63a0f25d390a

An IPv6 CIDR block is option and can be added *after* a subnet has been
created. Therefore, we should set it to `Computed: true`
Otherwise, a manually created IPv6 association will be removed on the
next terraform run
