Backport !3968 - Shell/Prevalidator: Replace manager operations by fees
Context
Changes in !3968 (merged) touch src/proto_alpha and we need them in snapshotted Protocol I. Cherry-picked first two commits from it using the following commands.
$ git checkout -b proto-i-backport-3968
$ git cherry-pick 2404edda6c23d92256ee3821da5986bfdcf430d5^..cf68440575c7152f1da0cb3b499d6bc58a41a42eSkipping Tezt changes because those depend on lots of other changes. But copied regression test outputs updates from 2707df52 because they are required for existing tests.
Manually testing the MR
