Get eraseMaxGeometry and eraseMinGeometry from dbus

Also, make findDevice return output parameters based on RVO.

With the change like in EntityManager JSON:
```
{
    "Name": "example_emmc",
    "Type": "EmmcDevice",
    "LocationCode": "location"
    "EraseMaxGeometry": 10000000000,
    "EraseMinGeometry": 5000000000,
}
```
and geometry values will be set to estoraged.

Tested:
- unit test pass:
```
5/7 util_test                        OK              0.05s
```
