Aquarium version 2.8.0

This release makes Docker configuration the default.

It is no longer necessary for non-developers to clone this repository,
and instead users should be using the Docker image available on Docker hub from
https://hub.docker.com/r/aquariumbio/aquarium:

• For production deployment, see the deployment instructions at aquarium.bio.
• For a local deployment, clone https://github.com/klavinslab/aquarium-local.

Changes:

• Rewrite entrypoint script so that provides more capabilities for configuring
  Aquarium.
• Change creation interface for users and groups to make it easier to script
  adding users.
• Parameterize database and application configuration with environment variables.
• Change puma configuration so that database.yml can contain ERB.
• Flip docker-compose files so that development mode is the default.
• Change Dockerfile to use a multi-stage build with a development stage,
  a production-build stage, and the stage for the production image.
• Make changes so that asset precompilation can occur in Docker production-build.
  Includes removing unnecessary monkey patches, and parameterizing database.yml
  file.
• Consolidated deployment configuration with previous docker configuration, and
  parameterized configuration using environment variables and a YAML file for
  instance details. Change S3 configuration to use either S3 or minio based on
  environment variables.
• Change biofab parameter key to "lab_agreement" and move agreement to YAML file.
• Refactor models to use predicates instead of chained checks of attributes.
• Pull source for aquadoc and anemone into components directory, and add
  components directory to build.
• Krill changes: add technician foot pedal interface, allow show block note,
  check, and bullet to take array of strings as arguments.
• Starting Aquarium in production using Docker will print the license.
• Add Sorbet type checking, and simplecov test coverage.
