build(deps): bump google.golang.org/grpc from 1.79.3 to 1.80.0 in /backend

[dependabot]

Bumps google.golang.org/grpc from 1.79.3 to 1.80.0.

Release notes

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

Release 1.80.0

Behavior Changes

• balancer: log a warning if a balancer is registered with uppercase letters, as balancer names should be lowercase. In a future release, balancer names will be treated as case-insensitive; see #5288 for details. (#8837)
• xds: update resource error handling and re-resolution logic (#8907)
  • Re-resolve all LOGICAL_DNS clusters simultaneously when re-resolution is requested.
  • Fail all in-flight RPCs immediately upon receipt of listener or route resource errors, instead of allowing them to complete.

Bug Fixes

• xds: support the LB policy configured in LOGICAL_DNS cluster resources instead of defaulting to pick_first. (#8733)
• credentials/tls: perform per-RPC authority validation against the leaf certificate instead of the entire peer certificate chain. (#8831)
• xds: enabling A76 ring hash endpoint keys no longer causes EDS resources with invalid proxy metadata to be NACKed when HTTP CONNECT (gRFC A86) is disabled. (#8875)
• xds: validate that the sum of endpoint weights in a locality does not exceed the maximum uint32 value. (#8899)
  • Special Thanks: @​RAVEYUS
• xds: fix incorrect proto field access in the weighted round robin (WRR) configuration where blackout_period was used instead of weight_expiration_period. (#8915)
  • Special Thanks: @​gregbarasch
• xds/rbac: handle addresses with ports in IP matchers. (#8990)

New Features

• ringhash: enable gRFC A76 (endpoint hash keys and request hash headers) by default. (#8922)

Performance Improvements

• credentials/alts: pool write buffers to reduce memory allocations and usage. (#8919)
• grpc: enable the use of pooled write buffers for buffering HTTP/2 frame writes by default. This reduces memory usage when connections are idle. Use the WithSharedWriteBuffer dial option or the SharedWriteBuffer server option to disable this feature. (#8957)
• xds/priority: stop caching child LB policies removed from the configuration. This will help reduce memory and cpu usage when localities are constantly switching between priorities. (#8997)
• mem: add a faster tiered buffer pool; use the experimental mem.NewBinaryTieredBufferPool function to create such pools. (#8775)

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a Azure member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work.

Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Looks like google.golang.org/grpc is up-to-date now, so this is no longer needed.
