show vdisks in donor mode correctly

[adameat]

donor vdisks - vdisks which are only exists to keep data for currently replicating main disks.

for "donor" vdisks:

1. display status that it's a donor, not a normal vdisk.
2. do not show replicated status and time remaining for replication.
3. do not show "Evict VDisk" button.
4. for list of groups in storage view do not filter by node id or pdisk id - group id is enough. (it should be done for all VDisks, not just donors).

here is an example of backend response for VDisk in donor mode.
