Description
pom.xml cleanups
- fix urls in pom.xml to point to new git repo and project page
- set failIfNoTests to false, so that it is possible to run mvn test -Dtest=TestSampler and so forth from the top level without getting "error: no tests were run" on one of the subprojects.
- don't run go tests when -DskipTests was specified
- shade commons-logging in htrace-core (so that we don't conflict with whatever version Hadoop or other software wants to use)
- remove old references to shading guava in the pom
