- Move some code into module part to avoid dependency from IStorage in SystemLog
- Remove extra headers from SystemLog.h
- Rewrite some code that was relying on headers that was included by SystemLog.h
v2: rebase
v3: squash move into module part with explicit template instantiation
(to make each commit self compilable after rebase)
v2: rebase against MergeTask
v3: rebase due to conflicts in src/Storages/MergeTree/MergeTreeDataMergerMutator.cpp
v4:
- rebase due to conflicts in src/Storages/MergeTree/MergeTask.cpp
- drop common/scope_guard_safe.h (not used)
From time to time 00975_move_partition_merge_tree test got failed, the
reason is that there is merge in progress that writes data to the source
table again:

And also remove cleaning of mutations since this will cause deadlock
after doing MOVE PARTITION under
currently_processing_in_background_mutex.
