fix: topology request during setup is blocking the MainThread, hanging until timeout

[viniarck]

Closes #75

Summary

• Avoid blocking setup() when loading topology by moving it to handle kytos/topology.topology_loaded

Local Tests

• Loaded this NApp and observed kytos/topology.topology_loaded and kytos/topology.updated, it loaded correctly without also the request timeout on setup()
