What does this PR do?

Adds option to use AWS instance ID as hostname

Description of the Change

When enabled, the plugin will attempt to use the AWS instance ID as the hostname.

Alternate Designs

Don't add an option, and only call the method when on an AWS host

some drawbacks to this approach are:

• difficult to detect accurately and when jenkins has migrated hosts
• not backwards compatible

some benefits to this approach are:

• closer to the agent behavior
• less configuration bloat
