Refactor class/instance loading and resolving in the SLI module
Code from the static class SvcLogicAdaptorFactory is moved to the SvcLogicClassResolver class. Class SvcLogicClassResolver is created as a bean in the blueprint xml file, not as singleton directly in the code. Then is injected via blueprint into the SvcLogicServiceImpl. Methods registerExecutor and unregisterExecutor from the SvcLogicServiceImpl class are removed - are not used anywhere. This change causes compilation error in the northbound repository. Fix for this error is here: https://gerrit.onap.org/r/#/c/ccsdk/sli/northbound/+/95053/ Issue-ID: CCSDK-1688 Change-Id: I26ce01b761ab5d17f1cc19e39af581b1963658a5 Signed-off-by: Samuel Kontris <samuel.kontris@pantheon.tech>
