Support MCP client communication with servers over Streamable HTTP transport

[Ashfaqbs]

Description:
Currently, the Python MCP client example demonstrates communication with an MCP server via the STDIO transport. However, MCP also defines a streamable-http transport type that enables communication over HTTP with streaming capabilities.

It would be valuable to have an example or feature in this repository that shows how to implement a client communicating with an MCP server using streamable-http. This would help developers understand how to:

Initialize and configure the client for HTTP-based streaming communication

Handle request/response cycles and event streams over HTTP

Compare differences in setup and behavior between STDIO and streamable-http transports

Providing this example would make the quick start resources more complete and allow developers to experiment with both major transport types defined in MCP.
