Auto-flush of a segment is not considered flush-completed.
So we need to buffer binlog paths generated by auto-flush.

**What type of PR is this?**
- [x] Feature

**What this PR does / why we need it:**
This PR supports boolean expression as DSL.
1. The goal of this PR is to support predicates
    like `A > 3 && not B < 5 or C in [1, 2, 3]`. 
2. Defines `plan.proto`, as Intermediate Representation (IR) 
    used between go and cpp. 
3. Support expr parser, convert predicate expr to IR
    in proxynode, while doing static check there
4. Support IR to AST in cpp, enable the execution

Now it's able to start multiple datanode, however, they will process the same insert data.
Further changes are needed to truly enable multiple datanode:

While registering, dataservice need to return different insert channels for different datanode.
