This is the minimal amount of work needed to be able to create a list of a subset of subnet IDs in a VPC, allowing people to loop through them easily when creating EC2 instances or provide a list straight to an ELB.
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)
```
```

* added .travis.yml and deploy.sh
* added deploy script, updated travis.yml to build topic- branches
* generate random string for hostname
* plan now produces output plan, apply now consumes outputted plan
* cleanup; sane defaults
* explicit build dirs
Many apps deployed to Heroku require that multiple buildpacks be
configured in a particular order to operate correctly.
This updates the builtin Heroku provider's app resource to support
configuring buildpacks and the related documentation in the website.
Similar to config vars, externally set buildpacks will not be altered if
the config is not set.
