POMs: reintroduced profile "extratest" for convenience ("long" build)

The profile includes also conntest, no separate profile for that module,
but we can run extra tests for any single module with -D... switch.
All is documented in main POM and testing/pom.xml.
State of Schrodinger is ... well, it's Schrodinger, so unknown. :-)

+    Extra test run with custom JVM args (we have 16g on CI server, but it works without args too),
+    runs just under 900 tests, skips distribution and any common unit/IT tests (~1h50m):
+    mvn clean install -P extratest,-dist -Dsurefire.args="-Xmx8g" -Dfailsafe.args="-Xmx8g -Duser.language=en"
+

+    Full build with extra tests for a single module, "-DskipTests" suppresses other default tests:
+    mvn clean install -P -dist -DskipTests -DskipStoryTests=false
+    See "extratest" profile in testing/pom.xml for all individual properties enabling extra tests.
