Better discussion of the pipeline pyramid

[binkley]

• card for merge with existing
• look what is a pipeline
• create page one

10k foot view

Current view is not nice to look at:
https://github.com/binkley/modern-java-practices/wiki/What-is-a-build-pipeline#the-ground-view

What should the discussion be on different parts of the pipeline?

• Build results
• Quality checks (code style, static analysis, etc)
• Unit tests
• Integration tests (within components of the build)
• System tests (mocks for databases, remote REST calls, etc)
• Acceptance tests

Discussion on tradeoffs for different checks & tests for:

• Local work before commit
• Local work before push
• CI (the whole enchilada; we're comfortable to deploy if all checks&tests are green)

Out of scope

• Badge to show the maturity of your build pipeline -- how many things (like mutation, security, etc testing) -- see A badge for build stability #387
• An "overall" badge combining each phase of the build
