Improved samples: added weather tool in AspNetCoreSseServer and option to connect via http to AspNetCoreSseServer.

[sabbadino]

Motivation and Context

Currently the QuickStartClient contains samples using stdio only , no samples using http.
The AspNetCoreSseServer has been modified to add a new MCP tool (GetWeather).
The QuickStartClient has been modified to accept "http" as argument: If "http" is provided, it will connect to AspNetCoreSseServerb via http.
The QuickStartClient has been modified to allow LLM to have the conversation history context.

How Has This Been Tested?

No changes in the library, just adding a sample.

Sorry for the delay in reviewing this. It is nice to have a non-authenticated HTTP client sample, and I do think it makes sense to allow LLM to have the conversation history context. I fixed the most recent merge conflicts and made a few other style changes, but the functionality is exactly the same. Thanks for contributing this!
