Subject: T6028: Fix QoS policy shaper wrong class_id_max and default_minor_id
The `class_id_max` is wrong due to `tmp.sort` of Strings
If we have class 5 and class 10 we get sorted max value 5, expected 10
```
>>> tmp = ['5', '10']
>>> tmp.sort()
>>> tmp
['10', '5']
>>>
>>> hex(5+1)
'0x6'
>>>
>>> hex(10+1)
'0xb'
>>>
```
This way we get wrong default maximum class value:
```
tc qdisc replace dev eth1 root handle 1: htb r2q 444 default 6
```
Expect:
```
tc qdisc replace dev eth1 root handle 1: htb r2q 444 default b
```
Fix this converting Strings to Integers and get max value.
