Implement artificial cache sepration To avoid repeated downloads, bazel has a cache of files, indexed by their (sha256) hash. If a file is requested with a hash already in cache, the file is taken from cache instead. However, in some cases, users think about a different identifier as canonical for that file than (the hash of) its contents, causing unexpected results when this identifier is updated but the sha256 sum is not. To avoid those cache hits, allow the canonical id to be specified in the download API. Design document: https://github.com/bazelbuild/proposals/blob/master/designs/2019-04-29-cache.md Closes #5144 as users can specify a canonical id, including the URL if they so desire, to make cache hits depend upon.

{Fast, Correct} - Choose two
Build and test software of any size, quickly and reliably.
Speed up your builds and tests: Bazel only rebuilds 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.
