Add SkycacheChannelStateAdvisor to shed requests upon overload.

This does not have any real effect yet, because nothing is adjusting
the request counts yet.

The existing solution can block Skyframe or serialization worker threads
when the cache is saturated starving CPU cores and build throughput,
turning an optional caching optimization into a potential latency
bottleneck. Non-blocking load shedding avoids thread parking and queue
contention entirely, seamlessly degrading excess work to local evaluation
on available cores while keeping network and memory strictly bounded.

Bazel

{Fast, Correct} - Choose two

Build and test software of any size, quickly and reliably.

  • Speed up your builds and tests: Bazel rebuilds only what is necessary. With advanced local and distributed caching, optimized dependency analysis and parallel execution, you get fast and incremental builds.

  • One tool, multiple languages: Build and test Java, C++, Android, iOS, Go, and a wide variety of other language platforms. Bazel runs on Windows, macOS, and Linux.

  • Scalable: Bazel helps you scale your organization, codebase, and continuous integration solution. It handles codebases of any size, in multiple repositories or a huge monorepo.

  • Extensible to your needs: Easily add support for new languages and platforms with Bazel's familiar extension language. Share and re-use language rules written by the growing Bazel community.
