Rename attributes like connected_link and connected_node to start with
an underscore.
This will prevent circular dependency and stack recursion depth error.
## Summary
Carrying on where Sunil left the task. Added more functionality to the DNS.
- DNS Server can keep a list of domain names that the DNS Client can request
- DNS Client has a cache of domain names that are valid from the DNS Server

## Summary
This pull request focuses on implementing key functionalities needed for network frame processing and database interactions. The primary changes are:
1. **Internal Frame Processing:** The logic has been implemented in various components like `NIC`, `Node`, `SessionManager`, and `SoftwareManager`. These changes enable the system to process incoming and outgoing network frames in a structured manner.
2. **Database Service and Client:** The `DatabaseService` simulates a SQL database server, while the `DatabaseClient` provides a client interface for connecting to this service. These functionalities have been built and integrated into the existing architecture.
3. **Networking and Communication:** Tests have been added to confirm that database queries can be sent over the network, demonstrating end-to-end functionality.
## Commits
- #1816 Simplified a bunch of stuff in the file system in prep for services and applications. Started adding the database logic. Waiting for the software manager/session manager work from another tick. Merge branch 'dev' into feature/1816_Database-Service-(Network-and-User-Interaction)
- #1816 Added the final pieces of the puzzle to get data up from NIC → session manager → software manager → service.
- #1816 DatabaseService now uses the send function when responding.
- #1816 Added database client. Installed the database client on the Web Server node in the UC2 network. Updated the integration test to query the DB server using the DB client.
- #1816 Added full documentation on the database client/server, and the internal frame processing process
- #1816 Fixed tests. Used node and link added number (id) in observation space.
## Test process
For testing these functionalities, the following steps were taken:
1. **Unit Tests:** Tests have been written to confirm that database queries can be sent over the network successfully.
2. **Integration Tests:** Manually tested the frame processing flow from NIC to Service/Application, ensuring the functionality behaves as expected.
3. **Database Queries** Executed sample SQL queries using the `DatabaseClient` to make sure it interacts correctly with the `DatabaseService`.
