Fix Sonar Issues in sli/core module
Few major issues *Remove unused imports To increase code readability *Replace the type specification with the diamond operator To reduce the verbosity of generics code *Add the "@Override" annotation above this method signature To increase code readability *Remove this unnecessary cast to "String" Unnecessary casting expressions pollutes code Issue-Id: CCSDK-87 Change-Id: I38952f5026a5c61af73ac16706e8ddc278566b13 Signed-off-by: surya-huawei <a.u.surya@huawei.com>
