Provide Libraries that enable basic functionality that most sandboxes require

Many of our guests have started to add thier own networking and disk implementations. We could provide common libraries and apis that enable easier integrations with common support

https://github.com/hyperlight-dev/hyperlight-sandbox/issues/14
https://github.com/hyperlight-dev/hyperagent#how-it-works

Start by reviewing the linked issues in hyperlight-unikraft and hyperlight-sandbox, then read the HyperAgent architecture described in its repository. Identify which networking, disk, or other sandbox integrations are common enough to define as shared libraries and APIs. Done requires an agreed scope and design for the proposed functionality.
