Implement distributed caching for Bazel

This patch implements distributed caching for Bazel using Hazelcast.
Hazelcast is used as a key value store that stores content of files
indexed by the digest of the file. The cache also stores the list of files
for an action. The key in this case is the digest from the key of the action
and the list of files.

In this change I also added the interface for remote execution. The
implementation will be added in a subsequent patch.

This change is only the first in a series of changes related to distributed
caching and remote execution. I plan to revise the APIs and implementation
in subsequent changes.

Bazel (Beta)

{Fast, Correct} - Choose two

Bazel is a build tool that builds code quickly and reliably. It is used to build the majority of Google‘s software, and thus it has been designed to handle build problems present in Google’s development environment, including:

  • A massive, shared code repository, in which all software is built from source. Bazel has been built for speed, using both caching and parallelism to achieve this. Bazel is critical to Google's ability to continue to scale its software development practices as the company grows.

  • An emphasis on automated testing and releases. Bazel has been built for correctness and reproducibility, meaning that a build performed on a continuous build machine or in a release pipeline will generate bitwise-identical outputs to those generated on a developer's machine.

  • Language and platform diversity. Bazel's architecture is general enough to support many different programming languages within Google, and can be used to build both client and server software targeting multiple architectures from the same underlying codebase.
