Bump google.golang.org/grpc from 1.76.0 to 1.77.0

[dependabot]

Bumps google.golang.org/grpc from 1.76.0 to 1.77.0.

Release notes

Sourced from google.golang.org/grpc's releases.

Release 1.77.0

API Changes

• mem: Replace the Reader interface with a struct for better performance and maintainability. (#8669)

Behavior Changes

• balancer/pickfirst: Remove support for the old pick_first LB policy via the environment variable GRPC_EXPERIMENTAL_ENABLE_NEW_PICK_FIRST=false. The new pick_first has been the default since v1.71.0. (#8672)

Bug Fixes

• xdsclient: Fix a race condition in the ADS stream implementation that could result in resource-not-found errors, causing the gRPC client channel to move to TransientFailure. (#8605)
• client: Ignore HTTP status header for gRPC streams. (#8548)
• client: Set a read deadline when closing a transport to prevent it from blocking indefinitely on a broken connection. (#8534)
  • Special Thanks: @​jgold2-stripe
• client: Fix a bug where default port 443 was not automatically added to addresses without a specified port when sent to a proxy.
  • Setting environment variable GRPC_EXPERIMENTAL_ENABLE_DEFAULT_PORT_FOR_PROXY_TARGET=false disables this change; please file a bug if any problems are encountered as we will remove this option soon. (#8613)
• balancer/pickfirst: Fix a bug where duplicate addresses were not being ignored as intended. (#8611)
• server: Fix a bug that caused overcounting of channelz metrics for successful and failed streams. (#8573)
  • Special Thanks: @​hugehoo
• balancer/pickfirst: When configured, shuffle addresses in resolver updates that lack endpoints. Since gRPC automatically adds endpoints to resolver updates, this bug only affects custom LB policies that delegate to pick_first but don't set endpoints. (#8610)
• mem: Clear large buffers before re-using. (#8670)

Performance Improvements

• transport: Reduce heap allocations to reduce time spent in garbage collection. (#8624, #8630, #8639, #8668)
• transport: Avoid copies when reading and writing Data frames. (#8657, #8667)
• mem: Avoid clearing newly allocated buffers. (#8670)

New Features

• outlierdetection: Add metrics specified in gRFC A91. (#8644)
  • Special Thanks: @​davinci26, @​PardhuKonakanchi
• stats/opentelemetry: Add support for optional label grpc.lb.backend_service in per-call metrics (#8637)
• xds: Add support for JWT Call Credentials as specified in gRFC A97. Set environment variable GRPC_EXPERIMENTAL_XDS_BOOTSTRAP_CALL_CREDS=true to enable this feature. (#8536)
  • Special Thanks: @​dimpavloff
• experimental/stats: Add support for up/down counters. (#8581)

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
