Refinements to RestApiCall plugin
Changes includes: 1) Check for null in JsonParser.convertToProperties() which can otherwise result in null pointer exception 2) Use logger built-in string formatting rather then string concatenation 3) Use StringBuilder for multiple string concatenations 4) Making utility classes final and defines private constructor for them 5) Added testcases/testpoints https://sonar.onap.org/component_issues/index?id=org.onap.ccsdk.sli.plugins%3Accsdk-sli-plugins#resolved=false|severities=CRITICAL Change-Id: Ic047b6d0369827a38a98c52e8365f1fe7266840f Issue-Id: CCSDK-67 Signed-off-by: Gaurav Agrawal <gaurav.agrawal@huawei.com>
