#### Description

Allow launching an EC2 instance with EC2 hibernation enabled.

EC2 supports launching instances that support hibernation by providing the appropriate configuration at runtime when an instance launches. The packer plugin currently does not support passing through this configuration.

#### Use Case(s)

- Greater control of instance lifecycle used for creating AWS images
- Creating images with instances with configuration parity with other EC2 instances

#### Potential configuration

```
hibernation_options {
configured = true
}
```
