Subject: [PATCH] `HttpLlm.appliation()` escapes some special characters.

ChatGPT allows only `/^[a-zA-Z0-9_-]+$/` characters in the tool calling function name. By the way, `$` and `%` characters are often shown in the URL path.

For such special characters, this PR replaces them to `_` character to successfully composing LLM function calling application from the OpenAPI document.
