Replace GraphQL Client with kotlin-wot Client for Agent Communication in LMOS runtime

[RobWin]

Problem Description:

The current system utilizes a GraphQL client to communicate with Agents. We aim to replace the existing GraphQL client with the kotlin-wot client. This transition will enable standardized interactions with Agents through their Thing Descriptions (TDs), which are supplied by the LMOS Operator.

Acceptance Criteria:

• The kotlin-wot client is successfully integrated into the system, replacing the existing GraphQL client.
• The system retrieves Thing Descriptions (TDs) from the LMOS Operator and utilizes them to interact with Agents via the kotlin-wot client.
