The WildFly Arquillian ManagementClient should not assume undertow is enabled

When using wildfly-arquillian with infinispan-server, the connection to the managed server breaks with the following exception:

java.lang.RuntimeException: org.jboss.as.arquillian.container.ManagementClient$UnSuccessfulOperationException: "WFLYCTL0030: No resource definition is registered for address [(\"subsystem\" => \"undertow\")]"
at org.jboss.as.arquillian.container.ManagementClient.getWebUri(ManagementClient.java:143)
at org.jboss.as.arquillian.container.ManagementClient.getProtocolMetaData(ManagementClient.java:160)
at org.jboss.as.arquillian.container.CommonDeployableContainer.deploy(CommonDeployableContainer.java:145)
at org.jboss.arquillian.container.impl.client.container.ContainerDeployController$3.call(ContainerDeployController.java:161)
at org.jboss.arquillian.container.impl.client.container.ContainerDeployController$3.call(ContainerDeployController.java:128)

at org.jboss.arquillian.container.impl.client.container.ContainerDeployController.deploy(ContainerDeployController.java:127)

This is because the client relies on the availability of the undertow subsystem, which might not necessarily be available (as is the case with infinispan-server).
