Yong Tang 158b2a1875 Add scope filter in /networks/<id>
This fix tries to add a `scope` in the query of `/networks/<id>`
(`NetworkInspect`) so that in case of duplicate network names,
it is possible to locate the network ID based on the network
scope (`local`, 'swarm', or `global`).

Multiple networks might exist in different scopes, which is a legitimate case.
For example, a network name `foo` might exists locally and in swarm network.

However, before this PR it was not possible to query a network name `foo`
in a specific scope like swarm.

This fix fixes the issue by allowing a `scope` query in `/networks/<id>`.

Additional test cases have been added to unit tests and integration tests.

This fix is related to docker/cli#167, moby/moby#30897, moby/moby#33561, moby/moby#30242

This fix fixes docker/cli#167
