developer environment setup script and docs

[amnonkhen]

Currently the setup of a developer's environment is a multi step process scattered between a few documents, code repos (hca-ebi-dev-team, ingest-kube-deployment) and collective memory.

Ideally it should be a simple process of running a single setup script that does all of:

• software setup
• verification of installed software
  • version verification
  • verification of required software that is not yet part of the automated installation (if does not exist, exit gracefully)
• repo clone
• cloud access setup: aws, gcp
• cluster access setup
• populate local mongo with prod data
• validate environment setup: build and startup of core, broker and ui

It is a common practice of have a Makefile in one the project's main repo to be this single setup script.
