[QA] Port change issue

[nikit91]

Hello,

In the Gerbil's QuestionAnswering branch, start.sh has the following argument passed to maven command:
-Dcargo.servlet.port=5004

However, I still get the error regarding port 8080 being unavailable:

[INFO] [en3.ContainerRunMojo] Resolved container artifact org.codehaus.cargo:cargo-core-container-tomcat:jar:1.9.11 for container tomcat9x
[INFO] [beddedLocalContainer] Tomcat 9.x Embedded starting...
[WARNING] [beddedLocalContainer] org.codehaus.cargo.container.ContainerException: Port number 8080 (defined with the property cargo.servlet.port) is in use. Please free it on the system or set it to a different port in the container configuration.
[ERROR] Starting container [org.codehaus.cargo.container.tomcat.Tomcat9xEmbeddedLocalContainer@7a5c6d8] failed
org.codehaus.cargo.container.ContainerException: Port number 8080 (defined with the property cargo.servlet.port) is in use. Please free it on the system or set it to a different port in the container configuration.

For now, I am using a work-around that involves providing the port directly in the pom.xml instead ( Ref: https://codehaus-cargo.github.io/cargo/Configuration+properties.html#Configurationproperties-MavenPlugin)

It seems that even after providing a port through the commandline the codehaus cargo plugin goes and checks availability of the default port first (8080).
