[PATCH 11/20] nvmet: introduce new members for ns-mgmt

[Chaitanya Kulkarni]

We update the target data structures to support ns-mgmt
commands. The new members for nvmet_ns are used to in the
create-ns command implementation. We use mount_path
of the nvmet_subsys to allow the user to initialize the
directory under which all the files for the respective
namespace(s) are created.
