feat(agents): support Databricks Agent Platform agents in the agent gateway (#45681)
* feat(agents): support Databricks Agent Platform agents in the agent gateway

Add a databricks_agent provider that speaks the MLflow ResponsesAgent wire
(Responses-shaped input, output_text items, output_text.delta SSE) to Model
Serving endpoints (/invocations or the unified /serving-endpoints/responses)
and Databricks Apps (/responses), with a PAT or OAuth M2M client credentials

Register it through the agents config block or the Admin UI agent catalog and
call it through /a2a/<agent> (message/send, message/stream) or model:
a2a/<agent> chat completions. The chat route now runs every completion-bridge
agent through its own provider, and attaches the minted Databricks OAuth token
for both bridge and URL agents. Consumed OAuth settings never reach the
provider call

* fix(agents): harden databricks_agent input, output, and OAuth handling

Non-text content parts answer 400 unless drop_params is set, a reply without
an output list answers 502, flat OAuth fields resolve an os.environ api_base,
the bridge debug log no longer echoes the request model, routing tests stub
only the HTTP boundary, and the catalog description fits the dropdown

* fix(agents): merge agent and client extra_headers on the a2a chat route, and reject an empty databricks_oauth block

* fix(agents): bridge only databricks_agent agents on the a2a chat route, keep the card url over a client api_base, and require workspace_url for a Databricks App

* refactor(agents): read the a2a chat bridge providers from a constants set instead of branching on a provider name

* fix(databricks_agent): let the configured credential win, reject malformed client extra_headers, and keep a missing endpoint name empty

* test(agents): drive the flat OAuth a2a send through the real bridge

* fix(agents): keep an empty databricks_oauth block ignored on url agents, as before this change

* fix(agents): accept bare App hosts, env service principals, and os.environ refs on Databricks agents

* fix(databricks_agent): address review caveats on chat bridging, params, and auth

Map max_tokens and max_completion_tokens to max_output_tokens and pass
temperature, top_p, and user, so /v1/messages works without drop_params.
Send A2A message metadata only with string values, answering 400 or
dropping the rest under drop_params. Join message items with a blank line
in both stream and non-stream replies. Cache the env service principal
token until shortly before it expires. Keep databricks_agent replies out
of the response cache.

On the chat bridge, let request fields win over the agent's stored params
while pinning the agent's api_base and api_key, and apply the agent's
static_headers between client and agent extra_headers, as /a2a does.
Resolve os.environ/ only for databricks_agent api_base and api_key instead
of every bridge provider. Ignore an unusable databricks_oauth block on URL
agents on chat, as at the merge base, instead of answering 400.

* test(internal_context): list the databricks agent token cache as process-local

* fix(databricks_agent): keep the agent's endpoint, input, and target out of client control

extra_body model and input answer 400, or are dropped under drop_params.
A client api_base or base_url never replaces the agent's card URL on the
bridge. Chat to a URL agent keeps its merge-base call, and an incomplete
databricks_oauth block on a URL agent keeps its merge-base ValueError.

* test(databricks): expect the merge-base 400 for a client api_base on agent chat

* fix(databricks): keep agent-owned inputs and identity headers out of a chat caller's reach

* fix(databricks): bound the agent-over-caller merge to two levels so it needs no recursion

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
