Move server-related shared utilities from common to framework

hdds-common project is shared between all the client and server projects. hdds-server-framework project is shared between all the server side services.

To reduce unnecessary dependencies (to Hadoop, for example) we can move all the server-side related classes (eg. rocksdb layer, certificate tools) to the framework from the common.

We don't need the rocksdb utilities and certificate tools on the client side.
