(take II) Control all devs by NM by default + filtering (iSCSI, FCoE) (#606745)
 
This version of patch differs only in that nm controlled dialog
was removed.

* All devices are set to NM_CONTROLLED in Network.__init__.
This solves the issue that for media installs without network
devices were not controlled by NM and thus not configurable
with nm-applet after install (the bug).

* For devices used for FCoE and iSCSI NM_CONTROLLED is modified
later (after storage initialization and FCoE/iSCSI setting)
in two places:

- before running nm-c-e
- FCoE devices are set to not controlled

- before writing ifcfg files to installed system
- FCoE devices are set to not controlled
- iSCSI devices *backing root* are set to not controlled
This can go away when
https://bugzilla.redhat.com/show_bug.cgi?id=607921
is fixed.

This change required splitting of isStorageDevice into three
finer functions (usedByFCoE, usedBy..., ...). Also note that
iSCSI case was fixed to count only devices actually used in route
to the target - code from dracutSetupString moved into function
ifaceForHostIP is used, as Hans suggested.

* Dialog for selecting devices controlled by NM is removed.
With all devices controlled by default it doesn't seem useful
enough.
