chore(deps): bump grpc-stub from 1.38.0 to 1.50.0

[dependabot]

Bumps grpc-stub from 1.38.0 to 1.50.0.

Release notes

Sourced from grpc-stub's releases.

v1.50.0

New Features

• okhttp: Added connection management features to okhttp server, including maxConnectionIdle(), permitKeepAliveTime(), and permitKeepAliveWithoutCalls() (#9494, #9544)
• binder: Add SecurityPolicies for checking device owner/profile owner (#9428)

API Changes

• api: Add LoadBalancer.acceptResolvedAddresses() (#9498). The method is like handleResolvedAddresses() but returns a boolean of whether the addresses and configuration were accepted. Not accepting the update triggers the NameResolver to retry after a delay. We are not yet encouraging migration to this method, as there is still a second future API change
• core: add CallOptions to CallCredentials.RequestInfo (#9538)

Bug Fixes

• auth: Fix AppEngine failing while retrieving access token when instantiating a blocking stub using AppEngineCredentials (#9504)
• core: Ensure that context cancellationCause is set (#9501)
• core: Update outlier detection max ejection logic to allow exceeding the limit by one, to match Envoy. (#9489, #9492)
• core: outlier detection to honor min host request volume (#9490)
• okhttp: Add timeout for HTTP CONNECT proxy handshake (#9586)
• xds: ringhash policy in TRANSIENT_FAILURE should not attempt connecting when already in connecting (#9535). With workloads where most requests have the same hash, ring hash should behave more like pick-first of slowly trying backends

Dependencies

• netty: upgrade netty from 4.1.77.Final to 4.1.79.Final and tcnative from 2.0.53 to 2.0.54 (#9451)

v1.49.2

Dependencies

• Bump protobuf to 3.21.7

v1.49.1

Bug Fixes

• xds: Fix a bug in ring-hash load balancing policy that, during TRANSIENT_FAILURE state, it might cause unnecessary internal connection requests on subchannels. (#9537)
• auth: Fix AppEngine failing while retrieving access token when instantiating a blocking stub using AppEngineCredentials (#9524)

Behavior Changes

• core: Update outlier detection max ejection logics, and min host request volume logics. (grpc/grpc-java#9550, #9551, #9552)

v1.49.0

New Features

• okhttp: Add OkHttpServerBuilder. The server can be used directly, but is not yet available via ServerBuilder.forPort() and Grpc.newServerBuilderForPort(). It passes our tests, but has seen no real-world use. It is also lacking connection management features
• okhttp: Add support for byte-based private keys via TlsChannelCredentials and TlsServerCredentials
• core: New outlier detection load balancer
• googleapis: google-c2p resolver is now stabilized

Bug Fixes

• core: Fix retry causing memory leak for canceled RPCs. (#9360)
• core: Use SyncContext for InProcess transport callbacks to avoid deadlocks. This fixes the long-standing issue #3084 which prevented using directExecutor() in some tests using streaming RPCs
• core: Disable retries with in-process transport by default (#9361). In-process does not compute message sizes so can retain excessive amounts of memory
• bazel: Use valid target name for services and xds when overriding Maven targets (#9422). This fixes an error of the form no such target '@io_grpc_grpc_java//services:services' for services and missing ORCA classes for xds. The wrong target names were introduced in 1.47.0
