Closes #1555

This PR adds some common enums & constants which will be used througjout the codebase. This PR code is equivalent to ccx_common_constants C file.

NOTE: Most of these enums are completely unrelated to each other and the only reason they are kept together for now is because they were kept together in C codebase. In the future when appropriate modules will be built, each of them will have to tranfered to their respective meaningful modules.
