ProcessMigrationIntegrationTest test methods fails on Jenkins

We looked into almost certain failures for:

• org.kie.processmigration.it.ProcessMigrationIntegrationTest.testReadinessCheck
• org.kie.processmigration.it.ProcessMigrationIntegrationTest.testMigration
• org.kie.processmigration.it.ProcessMigrationIntegrationTest.testLivenessCheck

All of them fails due Connect to localhost:8180 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1] failed: Connection refused (Connection refused)
