`libnmstate.show()` would include the info like bridge timer etc which
should not be considered when comparing between the previous state and
current state. Instead, using the the `libnmstate.show_running_config()`
which would filter out these kind of data.

The users want to apply the nmstate network state configuration to the
interface directly through the role, which necessitates the less
complexity of the network configuration and allows the partial
configuration on the network.
To warrant that the users are capable to apply the nmstate network state
configuration, add the support for the `network_state` variable.
