Added MCP server prompts functionality

[omarsrepo]

Added new code into the initialize() method of the MCPTools() class to fetch and list mcp server prompts and make it available to the agent as part of the MCPTools tooklit. Added a new get_entrypoint_for_prompt() function and imported it into MCPTools() class to aid in the above changes.

Summary

MCPTools() class only imported tools from an MCP server. The new code should help MCP servers expose their prompts (at least for custom MCP servers written with the python SDK).
