availability zone
Fixes#4752
According to the AWS Documentation, when `describing-vpn-gateways`
```
AvailabilityZone -> (string)
The Availability Zone where the virtual private gateway was created, if applicable. This field may be empty or not returned.
```
Therefore, if we pass an availability zone as part of vpn gateway, then it may come back as an empty string. If we set this empty string back to state, then the next plan will look as follows:
```
-/+ aws_vpn_gateway.vpn_gateway
availability_zone: "" => "us-west-2a" (forces new resource)
tags.%: "1" => "1"
tags.Name: "vpn-us-west-2" => "vpn-us-west-2"
vpc_id: "vpc-1e9da47a" => "vpc-1e9da47a"
Plan: 1 to add, 0 to change, 1 to destroy.
```
If the availability_zone comes back from AWS as an empty string, then we should not set it to state to avoid forcing a new resource for the user

This commit adds VPN Gateway attachment resource, and also an initial tests and
documentation stubs.

When VPC is detached from VPN gateway, its VpcAttachment stays in place
just with state changed to "detached". Since terraform was not checking
attachment state, it used to think VPC gateway was still attached.
An attempt to converge the tests into a standard naming scheme
- TestAccAWS for aws tests
- a `_basic` test for each suite, save a few that are quick (Network ACLs, for
example)
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.
