[Feature]: Support LangSmith "extra" field

[MarkRx]

The Feature

The "extra" field can be used to pass in custom metadata.

Example:

"extra": {
    "metadata": {
        "my-key": "my-value"
    }
},

See
REST API
Documentation
#4853

Motivation, pitch

The ability to pass in custom metadata using LangSmith with LiteLLM isn't possible at the moment.

hi @MarkRx - thanks for the issue do you want to do this through the LiteLLM proxy or on the LiteLLM python SDK ?
