fix: increase timeout value in integration tests

[gatici]

Description

Sdcore integrations tests are failing in v1.4 branch. When we check the logs, some applications(NMS, router, traefik) appear in maintenance status when the tests are run. This PR increases the timeout to check the applications status.
