## Description
Previously, the simple consensus may write to the statemachine in parrallel,
which may cause correctness problem and make the operations in log not be in
the same order of execution. This PR fixed this problem by adding synchronized
to Simple consensus operations.
<!--
In each section, please describe design decisions made, including:
- Choice of algorithms
- Behavioral aspects. What configuration values are acceptable? How are
corner cases and error
conditions handled, such as when there are insufficient resources?
- Class organization and design (how the logic is split between classes,
inheritance, composition,
design patterns)
- Method organization and design (how the logic is split between methods,
parameters and return types)
- Naming (class, method, API, configuration, HTTP endpoint, names of
emitted metrics)
-->
<!-- It's good to describe an alternative design (or mention an alternative
name) for every design
(or naming) decision point and compare the alternatives with the designs
that you've implemented
(or the names you've chosen) to highlight the advantages of the chosen
designs and names. -->
<!-- If there was a discussion of the design of the feature implemented in
this PR elsewhere
(e. g. a "Proposal" issue, any other issue, or a thread in the development
mailing list),
link to that discussion from this PR description and explain what have
changed in your final design
compared to your original proposal or the consensus version in the end of
the discussion.
If something hasn't changed since the original discussion, you can omit a
detailed discussion of
those aspects of the design here, perhaps apart from brief mentioning for
the sake of readability
of this PR description. -->
<!-- Some of the aspects mentioned above may be omitted for simple and small
changes. -->
