Fix knock on tabs/SONAR/Checkstyle issues
Changes in the last ONAP-REST review caused knock on changes in ONAP-PDP-REST. Those changes identified issues in two classes with tabs. While changing the tabs to spaces, some other easy to fix SONAR/Checkstyle issues were addressed. Issue-ID: POLICY-2132 Change-Id: I4e32089ada7b5095da0751993458cf7173cef064 Signed-off-by: liamfallon <liam.fallon@est.tech>
