Use latest surefire plugin and latest findbugs plugin (maven)
Remove source encoding properties - provided by parent pom
Remove tag from scm connection section, and fix a whitespace error
Remove unmodified pom sections already provided by parent

The surefire reports and findbugs sections still seem to be needed.
Extract findbugs, jacoco, and surefire plugin versions as pom properties

Preparing for further simplifications of the pom file
Move sections in pom to better match help:effective-pom layout

Moving sections makes it easier to compare the effective pom and the
actual pom so that redundant sections can be removed from the actual
pom.
Rationalize pom white space for easier comparison to effective pom
Remove redundant findbugs executions section from pom
Update Maven XSD location to match effective pom
Remove groupId of surefire plugin - reduce diffs to effective pom
Restore <tag>HEAD</tag> in scm section of pom - used in several other pom files
