Add smoke test for <deny-uncovered-http-methods/> tag

With Java Servlet 3.1 specification [1] comes possibility to use <deny-uncovered-http-methods/> tag in web.xml file. This new feature should be tested by a basic smoke test in WildFly testsuite.

Brief description of test case:

• set some of HTTP methods secured
• verify that these methods are accessible
• when anyone tries to use other than specified (i.e. secured) HTTP methods, status code 403 should be returned (according to specification)
