[OSC] Fix output format for osc share subnet create

The format of the osc share network subnet create command
output has been updated to return a list of hosts instead
of a dictionary, as we do for other commands in the client.
With this change, we are enhancing the consistency of the
client and the readability of the output.

Closes-bug: #1989818
