initial build for aws-node-termination-handler (#57980)

testing is not an option here since the project constantly queries AWS
Metadata Service and it keeps failing like this:

```bash
2025/06/30 12:02:52 WARN panic: There was a problem checking for spot ITNs: Unable to parse metadata response: Unable to get a response from IMDS: Get "http://169.254.169.254/latest/meta-data/spot/instance-action": dial tcp 169.254.169.254:80: connect: network is unreachable
```
