The commit reworks mgmt/mcumgr subsystem source code to remove
lib subdirectory and make it a little bit more flat.
It also moves all API interface files, which are supposed to be
visible by applications using MCUMgr, to interface sub-directories,
and exposes them with full paths; for example to include general
MCUMgr support, group registration and so on, user would now include:
<mgmt/mcumgr/mgmt/mgmt.h>
to additionally have control on File System group management
registration user would need:
<mgmt/mcumgr/mgmt/grp/fs_mgmt.h>
All internal headers have been removed from interface.
CMAkeLists.txt get significant rework and various MCUMgr subsystems
have been divided into separate sub-libraries.
