summary: Ensure that the network-observe interface works
details: |
The network-observe interface allows a snap to query the network status
information, using a dedicated unprivileged interface.
A snap which defines the network-observe plug must be shown in the
interfaces list. The plug must not be auto-connected on install and, as
usual, must be able to be reconnected.
A snap declaring a plug on this interface must be able to access read the
network status, the test sets up a network service to establish a known
state in the network to be queried.
