Initial Implementation of the CPP KVS

[joshualicht]

Initial Implementation of CPP KVS

Features:
-Supports Score Filesystem
-Supports Score JSON (Notice: Score JSON (nlohmann) has a problem with serializing Bool types)
-Supports Score Result and Errorcodes
-Behavior Unittests with 100% Line Coverage, 100% Function Coverage and 100% Branch Coverage
(except for brackets that are reported incorrectly),
Command to generate Coverage and create html results:
bazel coverage test_kvs_cpp --collect_code_coverage --instrument_test_targets --combined_report=lcov --experimental_generate_llvm_lcov --nocache_test_results --nostamp; genhtml --branch-coverage --output genhtml "$(find "$(bazel info output_path)" -name _coverage_report.dat)"
-Supports Bazel Build
-Doxygen Documentation

Not yet implemented/ To Dos:
-Set Default Value Handling TBD
-Add Score Logging
-Replace std libs with baselibs where possible
-Versioning of the CPP KVS (needs to be solved for CPP in general, not only for KVS)

Ci breaks because of other dependent libs as i understood . Should we merge it? @guysagnes
