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.

The current calculation `r2q` is wrong as it uses `Floor division`
but expecting `division`
This way `math.ceil` calculate wrong value as we expect
round a number upward to its nearest integer
For example for speed 710 mbits expected value `444` but we get `443`
```
from math import ceil
MAXQUANTUM = 200000
speed = 710000000
speed_bps = int(speed) // 8
>>> speed_bps // MAXQUANTUM
443
>>> speed_bps / MAXQUANTUM
443.75
>>>
>>>
>>> ceil(speed_bps // MAXQUANTUM)
443
>>> ceil(speed_bps / MAXQUANTUM)
444
>>>
```

The default `bandwidth` and `ceiling` should calculate values
based on <tag> bandwidth but currently it gets the value from
qos.base `/sys/class/net/{self._interface}/speed`
```
set qos policy shaper SHAPER bandwidth '20mbit'
set qos policy shaper SHAPER default bandwidth '95%'
set qos policy shaper SHAPER default ceiling '100%'
```
It causes wrong calculations for class `default` i.e
950Mbit for bandwidth (expected 95% of bandwidth, 19Mbit)
1Gbit for ceil (expected 100% of bandwidth, 20Mbit)
Gets incorrect values
```
r4# tc class show dev eth1
class htb 1:1 root rate 20Mbit ceil 20Mbit burst 1600b cburst 1600b
class htb 1:a parent 1:1 leaf 8053: prio 0 rate 200Kbit ceil 200Kbit burst 1Mb cburst 1600b
class htb 1:b parent 1:1 leaf 8054: prio 7 rate 950Mbit ceil 1Gbit burst 15200b cburst 1375b
```

QoS policy shaper-hfsc was not implemented after rewriting the
traffic-policy to qos policy. We had CLI but it does not use the
correct class. Add a basic implementation of policy shaper-hfsc.
Write the class `TrafficShaperHFS`

Add missed option `ceil` for QoS class 'trafficshaper'
|
|
QoS index priority should be used only for qostype 'shaper'
otherwise we set priority 2 times, that is incorrect.

There are wrong bandwidth calculations for the class
We shouldn't rely on interface speed but we should get this value
from 'shaper <tag> bandwidth xxx' if configured 'auto' or
bandwidth with '%'
Otherwise we can get unexpected rate for the class
% sudo cat /sys/class/net/eth0/speed
% -1
generated rate:
classid 1:17 htb rate -1000000

This makes transitions/updates faster and less error prone
