Feature request

There should be a generic ContentFilterException class that can be called when the llm content filter gets triggered.

Motivation

Currently when it gets triggered using langchain-openai with AzureChatOpenAI I get a openai.BadRequestError exception saying:
"The response was filtered due to the prompt triggering Azure OpenAI's content management policy. Please modify your prompt and retry. To learn more about our content filtering policies please read our documentation: https://go.microsoft.com/fwlink/?linkid=2198766"

If I were to use another model I would get a different exception and there would not be any way to catch all exceptions of this type.
This can be useful if you need to see which messages trigger a content filter when running an automated system.

Proposal (If applicable)

Create a generic ContentFilterException class that can be implemented by the different modules to catch that specific error. I looked at the source code and I couldn't find anything that does that, so I proposed it.

In the case of azure openai the error message reports:

{
  "error": {
    "message": "The response was filtered due to the prompt triggering Azure OpenAI's content management policy. Please modify your prompt and retry. To learn more about our content filtering policies please read our documentation: https://go.microsoft.com/fwlink/?linkid=2198766",
    "type": None,
    "param": "prompt",
    "code": "content_filter",
    "status": 400,
    "innererror": {
      "code": "ResponsibleAIPolicyViolation",
      "content_filter_result": {
        "hate": {"filtered": False, "severity": "safe"},
        "self_harm": {"filtered": False, "severity": "safe"},
        "sexual": {"filtered": True, "severity": "high"},
        "violence": {"filtered": False, "severity": "safe"},
      }
    }
  }
}
