Correct way to configure the TCK

[markt-asf]

I have manged, barring some challenges, to get the TCK passing with Tomcat 11. However, that required various configuration steps that seem rather hacky. I suspect I am not quite doing things the right way. I'd like to understand the right way to do these things so I can submit a PR to add the necessary configuration to the TCK to run with Tomcat.

I added to tomcat-11 profile to tck/pom.xml. This appears to the the correct way to do things so I am not concerned about these.

The configuration changes I am concerned about are:

• arquillian.xml. Placed in tck/common/src/main/resources, sets the user name and password required to deploy the test WARs to Tomcat. Also sets a number of system properties required by the tests.
• tomcat-users.xml. Placed in tck/common/src/main/resources, used to configure the user required to deploy the test WARs to Tomcat. Also creates a user required by some tests.
• ProviderConfiguration.xml. It was necessary to modify this file as the application context identifier needed to be changed to match the naming used by Tomcat.

Pointers to better/correct ways for each of the above welcome.
