remote: implement a naive action-scoped file system This change accompanies d480c5f [1] in that it registers an action-scoped filesystem that supports lazily fetching action inputs that are remotely stored outputs of an upstream action. While in theory any native java action in Bazel could do arbitrary file system operations in practice this is mostly useful for * AbstractFileWriteAction (calls Path.getInputStream()) * TemplateExpansionAction (calls Path.getInputStream()) * SymlinkAction (calls Path.(isFile|isExecutable|createSymbolicLink)()) * SolibSymlinkAction (calls Path.createSymbolicLink()) For Starlark actions we found that only ctx.actions.expand_template(...) directly interacts with the file system (via TemplateExpansionAction). All other methods on ctx.actions create spawns internally which are covered by d480c5f. Progress towards #6862.

{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.
