Evgenii Stratonikov 6f4908edc2 [#376] netmap: Make attributes a non-pointer slice
The speed of copying (which is done regulary for e.g. subnet changes)
is less, however it isn't on the hot path and the absolute time
difference is insignificant.
```
name              old time/op    new time/op    delta
NodeAttributes-8    96.2ns ± 1%   158.3ns ± 1%  +64.61%  (p=0.000 n=10+10)

name              old alloc/op   new alloc/op   delta
