refactor: first step to move all packages under src folder (#1226)

## Rationale

The final result will be moved all packaged under the `src` folder so
that we have a consistent and concise layout.

Take materialize as an example:
https://github.com/MaterializeInc/materialize/tree/main/src

## Detailed Changes

First step: move `src` to `src/server` while keep all the effective code
and config the same. So that we get rid of the special case first.

## Test Plan

Everything should keep AS IS and existing tests should pass.
