When creating a CloudWatch Metric for an Application Load Balancer it is
neccessary to use the suffix of the ARN as the reference to the load
balancer. This commit exposes that as an attribute on the `aws_alb`
resource to prevent the need to use regular expression substitution to
make the reference.
Fixes#8808.
A user has at some point explicitly specified in .terraformrc that
overriding should take place (unlike PATH based overrides), so this
should log as INFO rather than WARN.
It is still of value for debugging purposes, however!
I noticed that Terraform is not (anymore) parsing the value of environment variable `AWS_SECURITY_TOKEN` (which was re-added in May 2015: https://github.com/hashicorp/terraform/pull/1785)
Example ENV:
```
AWS_SECURITY_TOKEN="FQo...vgU="
AWS_ACCESS_KEY_ID="A...A"
AWS_SECRET_ACCESS_KEY="I...t"
AWS_DEFAULT_REGION="eu-west-1"
```
This errors with messages akin to "AWS was not able to validate the provided access credentials".
Setting `AWS_SESSION_TOKEN` instead of `AWS_SECURITY_TOKEN` on the other hand works just fine and seems to be in line with what is suggested in the code: d1ac7d3b2e/vendor/github.com/aws/aws-sdk-go/aws/credentials/env_provider.go (L69), making this whole thing a documentation change.
Happy to provide test cases or additional insights though!
It is currently very easy to miss that a provider/provisioner has a
local override in your .terraformrc, leading to unexpected behaviour
that can be difficult to debug as no information is output about the
overrides.
In order to satisify scenarios where a lifecycle is block is used, we
would need the AWS ALB name field to be autogenerated. WE follow the
same work as AWS ELB, we prefix it with `tl-lb-`

* fixed vpc rename bug
* Tweak the suggested fix
There was an assertion error in the fix, and after discussing we felt it was better to split the two changes to make them independant.
