Upgrade to napalm 3.4.1

[johannaengland]

Closes #2381.

The old version resulted it the warning
DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working
from collections import Iterable
Upgrading it to 3.4.1 fixes that and doesn't seem to influence anything else

Well, we don't have the worlds best test coverage, so it helps to check out the changelog of a library before attempting an upgrade.

I had a hard time finding one for NAPALM, so for future reference, it appears they just use GitHub releases as their changelog: https://github.com/napalm-automation/napalm/releases

There doesn't seem to be anything fishy in the changelog between 3.0 and 3.4, so I'd say this is probably fine.
