Introduce AnthropicClient and AnthropicClientAgent (#2769)
* Reference project Revert "Set up the Agent. Basic Example set up, boilerplate for connector, ran into signing issue." This reverts commit 0afe04f2 End to end working anthropic agent + unit tests Set up the Agent. Basic Example set up, boilerplate for connector, ran into signing issue. * Add pragma warning * - Remove Message type - tabbing fix white space in csproj - Remove redundant inheritance - Edit Anthropic.Tests' rootnamespace - Create AutoGen.Anthropic.Samples * short-cut agent extension method * Pass system message in the constructor and throw if there's system message in Imessages --------- Co-authored-by: luongdavid <luongdavid@microsoft.com>
