[Feature] SSH Plugin

## Summary

Allowing server commands (bash, powershell, etc.) to be called and return output.

## Motivation

This would enable automation that isn't handled easily by an API/DB. Basic example: IT creates a basic form/button that would call a command to disable someone in AD. HR could just put in a username a click disable. This could then send an email to a distro letting them know the user has been disabled. This is just an example, but the possibilities for scripting would be endless.

## Additional Context

Using JS would run the command locally, but the user may not be able to run the command due to vlan, permissions, or other factors. Having the command run from the server could resolve this. IT would be able to handle the logic, error checking and etc within their code. The main idea is just to be able to call commands from Appsmith to the server.

Security could be a concern since you may not want all users to have access to this feature. Permissions around it would be a bonus.
