Adding entries to .gitignore

Adding entries to .gitignore

When "mvn clean install" is run, the following is leftover:

Your branch is up-to-date with 'origin/master'.
Untracked files:
  (use "git add <file>..." to include in what will be committed)

	BRMSGateway/logs/
	BRMSGateway/sql/
	BRMSGateway/src/test/resources/META-INF/generatedCreate.ddl
	BRMSGateway/src/test/resources/META-INF/generatedDrop.ddl
	BRMSGateway/src/test/resources/failure.properties
	LogParser/logs/
	ONAP-PAP-REST/catalina.base_IS_UNDEFINED/
	ONAP-PAP-REST/pdps/
	ONAP-PAP-REST/sql/
	ONAP-PAP-REST/src/test/resources/generatedCreate.ddl
	ONAP-PAP-REST/src/test/resources/generatedDrop.ddl

	ONAP-XACML/src/test/resources/pdpstest/
	POLICY-SDK-APP/catalina.base_IS_UNDEFINED/
	PolicyEngineAPI/logs/
	PolicyEngineUtils/logs/

It is distracting when trying to "git add <Files>" to a new commit. Updating the
.gitigore to ignore these so they are not listed anymore.
