### Context
Related to #24718 and lots of past questions received in Slack, Stack Overflow, etc.
The UPGRADE guides are great for individual Symfony components/bundles, but we're lacking instructions to upgrade a whole Symfony app from 2.x to 3.x or from 3.x to 4.x.
In the past we had problems with the changes introduced in https://github.com/symfony/symfony-standard which were not documented in the main UPGRADE files.
### Proposal
We could:
1) Add a new section int he UPGRADE file to explain the upgrading process for whole Symfony apps. This is what this PR proposes (but it's still just a draft).
2) We could move the changes of this PR to a new article in the Symfony Docs.
3) We could move the entire UPGRADE files to the Symfony Docs and explain the changes for individual components and whole Symfony apps.
4) ... ?
