Add "make run" command

[suzil]

Makes for easier local development :slightly_smiling_face:

• Add a make run command for easier local development
• Move the test docker-compose.yml file to the root directory (this is more standard)
• Bump docker-compose config version to 3 (latest is best if it works!)
• Remove installing a separate docker-compose version as it seems like the version included by Travis works for running tests
• Add note to README on new Makefile command for local development
