Add empty PDisk object even if there is no PDisk field

AllocatedSize could be numeric or NaN, but not undefined

There could be no proper id, use index in such case. Array index will be always different from pdisk and vdisk ids, since ids include several numbers joined by dash (e.g. "1-1001")

in which cases there may be no StringifiedId and why cant we always use index
I dont mean to rework anything - I just dont understand (:

- If there is no data about PDisk, then there would be no id, so we use index to prevent undefined ids - with undefined ids there is a bug where new disks added on every rerender
- Generally it's not a good practice to use indexes as keys, since they could cause some unexpected behaviour if array is reordered or some elements added or deleted (and it's not recommended in react docs). So we use unique ids everywhere where it's possible. For the case of missing vdisks' pdisks there is no much difference, since they have no data and displayed the same way

what do these magic constant strings mean?
comment would be nice (and may be move to actual constants)

maybe enum and use it in isErasureWithDifferentDC ?

I don't like enums, you have to import them everywhere to satisfy TS, while for union string types every option will be suggested by autocomplete
