Release flow for Eclipse project

• [] Upversion to proper snapshot version (3.5.0-SNAPSHOT) if not done yet

• mvn org.eclipse.tycho:tycho-versions-plugin:set-version -DnewVersion=3.5.0.qualifier
• In addition, these files were modified manually:
• archetype/src/main/resources/archetype-resources/pom.xml
• archetype/pom.xml

• Plan work for new release: issues
• Create new PR check job (2021-09) by copying and updating reddeer.prcheck.2020-12
• Share the intent to participate in SimRel

• • New project release record must be created by M1
• • touch aggrcon file by M2

• Creating new project release

• https://projects.eclipse.org/projects/technology.reddeer -> Commiter Tools -> Create a new Release
• • Create a milestone(s) in release plan
• Next section is only valid if there are breaking changes in IP, features, etc, or one year Release review validity expires (last was done for 2021-06, so until 2022-03 we are ok)
• • Schedule Release Review after project release is created (1st of 3rd Wed. on each month)
• • Check if there is existing release review approved already, approval would last for whole year so there is no need for review or each milestone!
• • This review is pending; contact The Eclipse Management Organization (emo@eclipse.org) to make it public. (can be found under https://projects.eclipse.org/projects/technology.reddeer/releases/3.4.0 -> Review: -> 3.4.0 Release Review link)
• • Request for PMC approval: eclipse technology reddeer -> Committer Tools -> Communication -> Send Email to the PMC)
• • Get +1 on technology-pmc mailing list request: [pmc approval]
• • Create IP Log (https://dev.eclipse.org/ipzilla): eclipse technology reddeer -> Committer Tools -> Intelectual Property -> Generate IP log
• • IP log: [iplog]
• • Wait for release review is done on planned date after all above steps are fulfilled
• • Gitlab issue for [release review] with approval
• • Link CQs if there are any: see [iplog]
• • Do final release milestone

• Jump in SimRel Milestone release with offset +3
  this is probably M2 +3 as reddeer cannot be built unless we got full stack of packages in some update site and this is usually happening at the end of M1.
• RedDeer milestone releasing - MX, RCX, Final, includes:

• Implement changes, fixes, etc. to RD
• Release proper milestone via https://ci.eclipse.org/reddeer CCI
• Create Eclipse SimRel aggregation build repo gerrit commit, validate - https://ci.eclipse.org/simrel/job/simrel.photon.runaggregator.VALIDATE.gerrit/, push, see sub-tasks.

• Create new release tag in reddeer repository and upload artifacts using [github-project-automation] scripts
• Spread release note to proper mailing lists (reddeer-dev)
• Triage issues for next release, close, move, etc.

SubTasks:
