Subject: [PATCH] backports for beta 2.5.2 (#10737)

* version: bump beta to 2.5.2

* [CI] allow cargo audit to fail (#10676)

* [CI] allow cargo audit to fail

* [.gitlab-ci.yml] add a comment about cargo audit

* [Cargo.lock] cargo update -p protobuf

* Reset blockchain properly (#10669)

* delete BlockDetails from COL_EXTRA

* better proofs

* added tests

* PR suggestions

* new image (#10673)

* Update publishing (#10644)

* docker images are now built on k8s: test run

* copy check_sync.sh in build-linux job

* copy scripts/docker/hub/* in build-linux job

* removed cache var

* cleanup, no more nightly dockers

* cleanup in dockerfile

* some new tags

* removed sccsche debug log, cleanup

* no_gits, new artifacts dir, changed scripts. Test run.

* define version once

* one source for TRACK

* stop kovan onchain updates

* moved changes for two images to a new branch

* rename Dockerfile

* no need in libudev-dev

* enable lto for release builds (#10717)

* Use RUSTFLAGS to set the optimization level (#10719)

* Use RUSTFLAGS to set the optimization level

Cargo has a [quirk]() in how configuration settings are propagated when `cargo test` runs: local code respect the settings in `[profile.test]` but all dependencies use the `[profile.dev]` settings. Here we force `opt-level=3` for all dependencies.

* Remove unused profile settings

* Maybe like this?

* Turn off incremental compilation

* Remove colors; try again with overflow-checks on

* Use quiet CI machine

* Turn overflow checking back on

* Be explicit about what options we use

* Remove "quiet machine" override

* ethcore: enable ECIP-1054 for classic (#10731)

* config: enable atlantis on ethereum classic

* config: enable atlantis on morden classic

* config: enable atlantis on morden classic

* config: enable atlantis on kotti classic

* ethcore: move kotti fork block to 0xAEF49

* ethcore: move morden fork block to 0x4829BA

* ethcore: move classic fork block to 0x81B320

* remove trailing comma

* remove trailing comma

* fix chainspec

* ethcore: move classic fork block to 0x7fffffffffffffff
