Set up separate resource limits for each domain, project, and user in your resource groups

## Objective

Establish resource limits for each domain, project, and user within resource groups.

## Context

There is a need to manage resources effectively by setting specific limits based on domains, projects, and users. This will help in controlling resource usage.

## Scope

- **Included**: Setting resource limits for domains, projects, and users.
- **Not Included**: Changes to existing resource allocation methods outside of the specified limits.

## Success criteria

- Resource limits are successfully set for each domain.
- Resource limits are successfully set for each project.
- Resource limits are successfully set for each user.
- Budget allocation is implemented to restrict usage to defined limits.

## Risks and dependencies

- Potential resistance to changes in resource management.
- Dependencies on existing resource management systems for implementation.

## Other information

- N/A

JIRA Issue: BA-835

The issue names no files, tests, or entry points. Start by locating the existing resource-group allocation and budget logic, then clarify how domain, project, and user limits should interact. Done means agreed behavior is implemented and verified for all three scopes, including enforcement at the defined budget.
