Add Sync from Genesis Test

[kj4ezj]

Change Description

This reintroduces the EOSIO sync-from-genesis test, which takes 3-5 minutes and is configured to run on every commit like the other tests. It simply starts EOSIO on each major chain, waits for LIB to advance, then passes or fails accordingly.

I have also changed how the Docker container (previously called the "Contracts Builder" or the "Contracts Base Image") is built. Previously, it was built with the package builder steps only on builds against major branches or tags. It extended build time by about 7 minutes, as the package builders run in under 3 minutes and this step runs in about 10. Now I build and install EOSIO into the Ubuntu 18.04 Docker container with the other build steps, pushing it to Docker Hub tagged with ONLY the git commit. This takes about the same amount of time as the other build steps. Later in the build, once all tests have passed, the container is retroactively tagged with the git branch and git tag, if one exists. This means the container is available for use in tests (like the sync-from-genesis test) in under 10 minutes, but still guarantees that any container pulled by branch or tag contains working software.

Tested

Some example builds:

• Main Pipeline
  • Build 19512 -- eos:develop
  • Build 19513 -- eos:release/2.0.x
  • Build 19516 -- eos:release/1.8.x
• Sync Tests
  • Build 17 -- eos:develop
  • Build 18 -- eos:release/2.0.x
  • Build 19 -- eos:release/1.8.x
• Edge Cases
  • Build 11 -- sync test started manually before EOSIO build pushed base-image
  • Build 12 -- failed sync test step retried
  • Build 13 -- manually triggered sync test
  • Build 16 -- the build which triggered this one was cancelled
• Contracts
  • Build 957 -- eosio.contracts pipeline pulls these images by branch
  • Build 958 -- eosio.contracts pipeline pulls these images by commit
