build(deps): Bump google.golang.org/grpc from 1.48.0 to 1.74.2

[dependabot]

Bumps google.golang.org/grpc from 1.48.0 to 1.74.2.

Release notes

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

Release 1.74.2

API Changes

• balancer: add ExitIdle method to Balancer interface. Earlier, implementing this method was optional. (#8367)

Behavior Changes

• xds: Remove the GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST environment variable that allows disabling the least request balancer with xDS. Least request was made available by default with xDS in v1.72.0. (#8248)
  • Special Thanks: @​atollena
• server: allow 0s grpc-timeout header values, which older gRPC-Java versions could send. This restores the behavior of grpc-go before v1.73.0. (#8439)

Bug Fixes

• googledirectpath: avoid logging the error message Attempt to set a bootstrap configuration... when creating multiple directpath channels. (#8419)

Performance Improvements

• transport: reduce heap allocations by pooling objects and avoiding method-to-closure conversions. (#8361)
• transport: reduce heap allocations by re-using mem.Reader objects. (#8360)

Documentation

• examples: add examples to demonstrate enabling experimental metrics using the OpenTelemetry plugin. (#8388)
  • Special Thanks: @​vinothkumarr227

Release 1.74.1

Version 1.74.1 retracts release v1.74.0 and itself. Release 1.74.0 was accidentally tagged on the wrong commit and should not be used. Version 1.73.0 should be used until 1.74.2 is released.

Release 1.74.0 was accidentally tagged on the wrong commit and should not be used. Version 1.73.0 should be used until 1.74.1 is released.

Release 1.73.0

New Features

• balancer/ringhash: move LB policy from xds/internal to exported path to facilitate use without xds (#8249)
• xds: enable least request LB policy by default. It can be disabled by setting GRPC_EXPERIMENTAL_ENABLE_LEAST_REQUEST=false in your environment. (#8253)
• grpc: add a CallAuthority Call Option that can be used to overwrite the http :authority header on per-RPC basis. (#8068)
• stats/opentelemetry: add trace event for name resolution delay. (#8074)
• health: added List method to gRPC Health service. (#8155)
  • Special Thanks: @​marcoshuck
• ringhash: implement features from gRFC A76. (#8159)
• xds: add functionality to support SPIFFE Bundle Maps as roots of trust in XDS which can be enabled by setting GRPC_EXPERIMENTAL_XDS_MTLS_SPIFFE=true. (#8167, #8180, #8229, #8343)

Bug Fixes

• xds: locality ID metric label is changed to make it consistent with gRFC A78. (#8256)
• client: fail RPCs on the client when using extremely short contexts that expire before the grpc-timeout header is created. (#8312)
• server: non-positive grpc-timeout header values are now rejected. This is consistent with the gRPC protocol spec. (#8290)
  • Special Thanks: @​evanj
• xds: fix reported error string when LRS load reporting interval is invalid. (#8224)
  • Special Thanks: @​alingse
