### Feature type

New Feature

### Feature Summary

Add Organizations to the EDAServer to allow multiple teams to use the tool.
Add the option to specify Container Groups for each organiation, a resource, which like in AWX, will allow us to specify the namespace and resources for the decision environment pods.

### Steps to reproduce

You will be able to create via the UI the organizations and instance/container groups as an admin user

### Current results

Currently all the decision environment pods are created with built in resources and in the namespace the eda server is deployed in.

### Sugested feature result

You can specify for users in a certain organization which namespaces/resources the decision environment pods they create are created in.

### Additional information

_No response_

No files, tests, or entry points are named. Start by tracing how the UI creates organizations, instance or container groups, and decision environment pods; done means organizations can scope users and specify the namespaces and resources used for their pods.
