Before this PR, DataNode considered auto-flush a valid flush
complete. It's wrong. So I open this PR to correct this behaviour
in DataNode.
Now binlog paths from auto-flush will be buffered in replica,
waiting until the manul flush to save into etcd all together.

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

Pass a parameter `IsExpr` from proxy to query node, so query
node can create search plan according to the variable `IsExpr`.
It makes `segcore` unnecessary to distinguish `dsl` or `expr`
using dynamic exception. When `IsExpr` is set to true, query
node will call `CreatePlanByExpr` according to the passed
information about expression. Otherwise query node will keep
still to use `CreatePlan` according to the `dsl` information. At
the same time, this pr adds some unittests to `CreatePlanByExpr`,
these unittests translate already exist case with `dsl` to case with
`expr`.

**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
