qa: add sourcegraph/server upgrade test, candidate images in QA (!14974) · Merge requests · Administrator / sourcegraph

Administrator requested to merge ci/sourcegraph-upgrade into main Oct 22, 2020

Created by: bobheadxi

Adds a new step in QA pipeline to attempt a Sourcegraph upgrade from defined previous version
Change QA steps to run after candidate images publish, so that the candidate images themselves can be used in testing
Change QA tests that use insiders images to use the appropriate candidate image for the commit being tested instead.
Unify test scripts (init-server.go, setup-*.sh, cleanup-*.sh) shared amongst the tests
Prevent secrets from being revealed on source /root/.profile
Move Code-Intel tests to QA
Add labels with descriptions for all tests

Make sure candidate images are always available for QA tests
Credentials for pulling candidate images in QA vagrant
Automation for updating MINIMUM_UPGRADEABLE_VERSION on release (probably via a new config option in https://github.com/sourcegraph/sourcegraph/pull/15154, like minimumSupportedVersion? or just do some maths from the current release) => will open a follow-up issue, hardcoded for now
