Storaged drop-in replacement for UDisks2

Summary

Storaged extends UDisks2 API by exporting several enterprise features (by plugins), such as LVM2 and iSCSI. This project is a drop-in replacement for UDisks2, either from D-Bus or binary point of view. The main motivation of this change is to provide the unified D-Bus API for all the clients who are willing to manage LVM2, iSCSI, Btrfs, BCache, LSM and ZRam.

Tracker bug: <will be assigned by the Wrangler>

Detailed Description

Aim of Storaged is to provide unified higher level management interface for various clients who are willing to query and manage storage bits of the system. We plan to replace UDisks2 by Storaged, since the Storaged itself is the fork of UDisks2 and these 2 projects in its core haven't diverged so much (Storaged got some improvements which popped up while using it).

Benefit to Fedora

The drop-in replacement is beneficial for Fedora because currently, there are 2 similar projects (one derived from the other). Since, Storaged can export the same API as UDisks2 does, but with several enterprise extensions, it is natural to replace one daemon with the extended one.
