## What do these changes do?

<!-- Please give a short brief about these changes. -->
As titled, support Multiple Matches in IR Core

1. From now, the logical plan will contain contain a dummy `RootScan`
after initialization by default. This dummy `RootScan` may be later used
to support multiple `scan`.
2. When a plan of a pattern matching is append to a node, if the plan is
naive plan, it will directly append to the assigned node. Otherwise, it
the plan is extend plan, then it must have its own scan operator, so it
have to be append to the dummy `RootScan`
3. When a sink operator is append to the logical plan, it suggests that
the logical plan building is finished. Therefore, it will call
`clean_redundant_nodes` method to clean useless nodes. There are two
kinds of reduandant nodes: `Scan `node with no child and dummy
`RootScan` with zero or only single child.
