Some minor refinements in CCSDK SLI Core module
Fix few Critical/Major sonar issues in CCSDK SLI Core module * Define and throw a dedicated exception instead of using a generic one * Either log or rethrow the exception * Change "try" to a try-with-resources * Remove useless assignment to local variable * Use built-in logger method string formatting instead of string concatination * code indentation Change-Id: I83dc1fb931b8021118e259c722f7dfbc1621dce8 Issue-Id: CCSDK-67 Signed-off-by: Ramu N <ramu.n@huawei.com>
