Create Standards for working with Bacalhau

[aronchick]

ETA: 2023Q1

• [ ] Please port this - https://dotmesh.com/blog/our-engineering-principles/ - to bacalhau website (@aronchick can do most)
• [ ] Please detail the path to coding and contributing. E.g. for someone who knows go and git, what are the specific commands they need to do to contribute:

1. create a new branch git checkout -B new_branch
2. push sync this branch with origin - git branch --set-upstream-to=origin/new_branch new_branch
3. contribute, and test frequently. e.g. code, make test, code, make test
4. rebased from main frequently - git checkout main; git pull; git checkout new_branch; git merge main; make test
5. once you're done, rebase to the point at which you first branch from main
6. run one more test
7. one more merge from main
8. now push your changes to the repo
9. go do a PR
