[Integration Tests] - Replace use of tomcat:7.0.75-jre8 in tests with higher version which can work on JDK 11
Issue Overview
We have enforced JDK 11 now, and tomcat:7.0.75-jre8 is widely used in Dockerfile in integration tests. The container starts with JDK8 but will try to load the tests servlets compiled in JDK 11 which will lead to container error:

Additional Information
JDK: 11
main branch
I see a https://github.com/arquillian/arquillian-container-tomcat/tree/main/tomcat-managed-10 from the coming rquillian-container-tomcat:1.2.1 , maybe we can consider of migrating to use tomcat 10 in Dockerfile for integration tests.
Hi @gaol - similar to #1303 and the related #1306 - this issue could be fixed already by #1317, which takes into account latest changes, and also brings fixes and updates which are all relevant to resume proper Docker integration tests. I took inspiration from your comments and assigned myself to the issues as well.
