This introduces a series of Docker images for running Review Bot

workers. Since there are so many tools, and not all of them are needed

for all deployments, Review Bot is split into a series of Docker images

for workers, focused on:

Base support for tools without external dependencies
C analysis
Go analysis
Java analysis
JavaScript analysis
Python analysis
Ruby analysis
Rust analysis
shell script analysis
The multi-language FBInfer tool
The multi-language PMD tool

There is no comprehensive "all" image, but it's likely not needed.

In the upcoming documentation, we'll offer guidance on how to build

custom Docker images that use the explicit tools people need.
The images are currently built only for x86 architectures. ARM should

mostly be supported by the tools, with the exception of FBInfer.

Built all the images and launched them in a docker-compose.yaml.
Successfully performed reviews with all tools.
(There were issues with the RabbitMQ image crashing and restarting,

but this seems to be a Docker on M1 issue).
