[regression] l23 network module cannot replug interfaces between bridges

[Vladimir Kuklin]

Fuel Library version: fuel-library9.0-9.0.0-1.mos8458.noarch

this bug is related to https://launchpad.net/bugs/1592998

Steps to reproduce:

1. Change network_scheme on the node by swapping incorrectly plugged interfaces, e.g. between management and storage bridges.
2. Run netconfig manifest

Expected result:

1. Interfaces are swapped

Actual result

1. Interfaces are swapped in interfaces file, but they are not reconfigured in runtime.

This affects one of the most frequent cases when a user put an incorrect configuration of interfaces onto the node and it errored during the deploy (including the case when it was in 'ready' status previously) and wants to fix the things by swapping interfaces.

This should be considered as a high bug as a user can break the cluster networking configuration and it will be really hard to unbreak it.
