Schema

We add a relation entity(IncentivePosition) for getting more detail information of staked positions which is used elyfi-web. Position's staked status meaning is also modified. In our repo, it means that the position is owned by the Staker. When DepositTransferred event is emitted, the status is udpated to false.
