### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Description
As [discussion](https://docs.google.com/document/d/1VafP0gu5o8WCYaII1mDjElseaJEOnKF0Ai4bxDIfVQE/edit) in the Dev meeting, I'm propose the Compute Only Node in doris.
A Compute Node(CN) will be different from BE as these aspects:
1. No any storeage in CN node. These will be no any tablet schedule to any CN node.
2. Only support the federation query such as hms table and es table.
3. Can be asigned the plan node except the table scan node when the workload is heavy in the be node.
4. Can be added or delete immediately.
### Solution
In my idea, I will impl this feature as these step:
1. Introduce the node type to doris, and the table creation and tablet scheduler will control the storage only assign to the BE nodes.
2. Support the olap query plan running on the CN node when workload is heavy
3. Impl the graceful shutdown when the doris pipeline engine is ready
