feat(vertex_ai)!: use HTTP/2 httpx client for search_api vector store (#40631)

* build(deps): add h2 to proxy extra so vertex search HTTP/2 is on by default

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(http_handler): isolate ssl context for http2 clients

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(http): add an HTTP/2 opt-out and harden the Vertex AI Search HTTP/2 client

litellm.http2 is now unset by default, so http2: false or LITELLM_HTTP2=False
turns the provider's HTTP/2 default off. A caller's own SSLContext keeps the
search on HTTP/1.1, the HTTP/2 async client honors DISABLE_AIOHTTP_TRUST_ENV,
forced IPv4 transports get the CA bundle and client cert, and vector store
search retries once when the server drops the connection with a GOAWAY.

* fix(http): retry vector store search only on HTTP/2 GOAWAY and keep aiohttp pool and proxy behavior

Scope the one retry to a connection Google closes with an HTTP/2 GOAWAY and
log it. When HTTP/2 replaces the aiohttp transport, keep aiohttp's idle
keepalive and connection cap, and only then skip env proxies under
DISABLE_AIOHTTP_TRUST_ENV, so the global LITELLM_HTTP2 toggle keeps HTTPS_PROXY

* test(http): cover the vector store search GOAWAY retry in unit tests and drop duplicate SSL cache comments

* fix(http): open another HTTP/2 connection once 100 streams are in use

httpcore keeps every request to an origin on one HTTP/2 connection and caps it at 100 concurrent streams, so request 101 and later waited with no timeout. The handlers now spread requests over extra connections, opening one only when every open connection has 100 streams in flight. The force_ipv4 wire tests now cover ssl_verify=False and the client certificate.

* fix(vertex_ai): reuse one Vertex search OAuth token across searches

Every vector store search built a new search config, so the token cache it carries was thrown away and each search fetched a new Google OAuth token with a blocking call on the event loop. Under a burst of searches that blocking fetch held back every HTTP/2 response. The provider config is now shared, so searches with the same credentials reuse one token until it expires.

* fix(http): keep the HTTP/2 connection spread within the connection cap

* fix(http): keep sync vertex search on HTTP/1.1, since httpcore's sync HTTP/2 is not thread-safe

httpcore 1.0.9 hands two threads the same HTTP/2 stream id, so threaded sync
searches failed with protocol errors. Only the async client, which the proxy
uses, now defaults to HTTP/2, and the sync connection spread is removed.

* fix(http): split the connection cap across HTTP/2 lanes

Each lane had its own pool with the full connection cap, so an origin answering
HTTP/1.1, or several origins on one client, could exceed max_connections once
more than 100 requests were in flight. Lanes now open only while lanes times
100 streams stay under the cap, and each lane pool gets at most 100 of it.

* test(http2): scope wire-test peer logs to each fixture instance

* fix(http2): keep TE, force_ipv4 trust, evicted-client and opt-out behavior on the HTTP/2 path

- drop TE values other than trailers on https requests through the HTTP/2 spread, since h2 refuses them
- force_ipv4 transports keep httpx's default trust store (SSL_CERT_DIR) unless SSL is configured
- the evicted client closer asks the HTTP/2 spread whether a request is in flight
- LITELLM_HTTP2 set to 0, no or off, and a quoted "false" http2 setting, opt out of HTTP/2
- the wire test's held-search barrier waits on an event instead of polling

* fix(http2): count proxy-mounted transports when checking an evicted client for in-flight requests

* test(http2): move the HTTP/2 eviction cases that open a loopback server into the integration wire tests

* fix(http2): read an unquoted http2: 0 as off and free the stream slot of a response dropped without closing

* fix(http2): free the stream slot of a partly read response dropped without closing

* test(http2): check that the evicted client and its stream close after a partly read response is dropped
