Fixes: #13588
It was pointed out in #13588 that we don't need to ForceNew on a change
of IPv6 CIDR block. The logic I decided to implement here was to
disassociate then associate. We should only be able to be associated to
1 IPv6 CIDR block at once. This feels like a risky move. We can
disassociate and then error on the associate. This would leave us in a
situation where we have no IPv6 CIDR block associated
The alternative here would be that the failure of association, triggers
a reassociation with the old IPv6 CIDR block
I added a test to make sure that the subnet Ids don't change as the ipv6
block changes. Before removing the ForceNew from the ipv6_cidr_block,
the test results in the following:
```
=== RUN TestAccAWSSubnet_ipv6
--- FAIL: TestAccAWSSubnet_ipv6 (92.09s)
resource_aws_subnet_test.go:105: Expected SubnetIDs not to change, but both got before: subnet-0d2b6a6a and after: subnet-742c6d13
```
After the removal of ForceNew, the test result looks as follows:
```
=== RUN TestAccAWSSubnet_ipv6
--- PASS: TestAccAWSSubnet_ipv6 (188.34s)
```
```

This landed in aws-sdk-go yesterday, breaking the AWS provider in many places:

Here, with much sedding, grepping, and manual massaging, we attempt to
catch Terraform up to the new `awserr.Error` interface world.
