Fix policy/common checkstyle issues

Fix policy/common checkstyle issues

The root pom.xml had a syntax error in a declaration. The suppressions
xml was not being found by the sub-modules. It was better to create a
copy in each of the sub-modules where we will not be fixing
abbreviations or the interface declarations in own java file.

Added specific checkstyle files for each submodule.

One interesting note for the InheritDoc tag. It seems that the mvn
compile has a bug that interprets these as missing a period after
the tag. Even though the parent interface has it correctly. It was
easier to just remove it than duplicate.

There are new JIRA's for that work to be done in Dublin.

Fixed some spacing in pom's.
