mSTS and mMUCH changes from march 2022 runs

Introduces support for mMUCH unpacking in the CRI world + working online monitoring for both systems + various fixes (see commits messages)

Draft status: To be rebased (should be trivial) and merged only after !809 (merged) is merged

Reviewers: @a.toia and @v.singhal (not assigning as both approval needed in my opinion)
