#### What did we implement:
in the Opendax, withdrawal limitation was handled by a model named `WithdrawLimit`, 
but for deposit limitation, there was no way.<br />
so by following existence rules, we create a new model and called it `DepositLimit` with the same columns, 
and those columns are :


| Name | Type | Description |<br/>
| ---- | ---- | ----------- |<br/>
| id | integer | Unique table identifier in database. |<br/>
| group | string | Member group for define limits. |<br/>
| kyc_level | string | KYC level for define limits.|<br/>
| limit_24_hour | double | 24 hours limit. |<br/>
| limit_1_month | double | 1 month limit. |<br/>

and also we added a new column to the  mentioned models by name: `kind` to support `fiat` and `coin` limitation<br/>
| Name | Type | Description |<br/>
| ---- | ---- | ----------- |<br/>
| kind | integer | Withdraw or Deposit kind (coin or fiat).|<br/>

before creation a withdrawal or deposit record by the user, 
we implemented a new function called `verify_limits` that check the user reached limitation or not, 
then permit the new withdraw or deposit record to be created.

### TODO
implement admin side include APIs (tower panel) for deposit limitation part
