Fix sonar code coverage issue in distribution

The jacoco plugin settings in oparent is for creating coverage report
for each sub-module sepeartely. That leads to coverage missing in the
report if the test cases & actual classes are in different sub-module.
Overiding the setting in distribution to create a consolidated report of
all sub-modules in one report.
