Add `Deploy` task for `8.3`

## Problem
With the removal of module hot-loading and the module loading servlet, the current developer experience for module's targeting `8.3` is poor.
The feedback time between making changes/compiling, manually uploading, and manually restarting the gateway is very long.

## Suggestion
The new `8.3` REST API allows for loading modules and restarting the Gateway.

I suggest that the `gradle-module-plugin` be updated with a new `8.3` specific `Deploy` task to:
1. Upload a module.
2. Restart the Gateway.

This would bring things back to feature parity with the `8.1` developer experience.

Start by locating the gradle-module-plugin's existing 8.1 Deploy task and compare it with the new 8.3 REST API described in the issue. The work is complete when an 8.3-specific Deploy task uploads a module and restarts the Gateway, restoring the stated 8.1 developer experience.
