Bumps [google.golang.org/grpc](https://github.com/grpc/grpc-go) from1.69.4 to 1.70.0.<details><summary>Release notes</summary><p><em>Sourced from <ahref="https://github.com/grpc/grpc-go/releases">google.golang.org/grpc'sreleases</a>.</em></p><blockquote><h2>Release 1.70.0</h2><h1>Behavior Changes</h1><ul><li>client: reject service configs containing an invalid retryPolicy inaccordance with gRFCs <ahref="https://github.com/grpc/proposal/blob/master/A21-service-config-error-handling.md">A21</a>and <ahref="https://github.com/grpc/proposal/blob/master/A6-client-retries.md">A6</a>.(<ahref="https://redirect.github.com/grpc/grpc-go/issues/7905">#7905</a>)<ul><li>Note that this is a potential breaking change for some users usingan invalid configuration, but continuing to allow this behavior wouldviolate our cross-language compatibility requirements.</li></ul></li></ul><h1>New Features</h1><ul><li>xdsclient: fallback to a secondary management server (if specifiedin the bootstrap configuration) when the primary is down is enabled bydefault. Can be disabled by setting the environment variable<code>GRPC_EXPERIMENTAL_XDS_FALLBACK</code> to <code>false</code>. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/7949">#7949</a>)</li><li>experimental/credentials: experimental transport credentials areadded which don't enforce ALPN. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/7980">#7980</a>)<ul><li>These credentials will be removed in an upcoming grpc-go release.Users must not rely on these credentials directly. Instead, they shouldeither vendor a specific version of gRPC or copy the relevantcredentials into their own codebase if absolutely necessary.</li></ul></li></ul><h1>Bug Fixes</h1><ul><li>xds: fix a possible deadlock that happens when both the clientapplication and the xDS management server (responsible for configuringthe client) are using the xds:/// scheme in their target URIs. (<ahref="https://redirect.github.com/grpc/grpc-go/issues/8011">#8011</a>)</li></ul><h1>Performance</h1><ul><li>server: for unary requests, free raw request message data as soon asparsing is finished instead of waiting until the method handler returns.(<ahref="https://redirect.github.com/grpc/grpc-go/issues/7998">#7998</a>)<ul><li>Special Thanks: <ahref="https://github.com/lqs"><code>@​lqs</code></a></li></ul></li></ul><h1>Documentation</h1><ul><li>examples/features/gracefulstop: add example to demonstrate servergraceful stop.
