Generic LLM Connector

Generic LLM Connector ===================== This add-on lets Splunk administrators configure reusable LLM providers and connections, then call them from a customized search command named `llm`. Provider -------- A provider stores the transport details needed to reach an LLM API， currently support `OpenAI-compatible` or `Anthropic-compatible` endpoints Connection ---------- A connection stores the runtime selection details used by the search command which includes - name - provider reference - model Only one connection can be marked as the global default. If the `llm` command is called without `connection=`, the add-on uses that default connection.
