Use pdisk/info endpoint for PDisk page

[artemmufazalov]

Based on ydb-platform/ydb#5195

pdisk properties:

• node_id - pdisk_id (I expect it to be in the header)
• somewhere on the top, where Restart button is - DecomissionStatus (DecommitStatus)
• BSC/Type, Path, Guid, SerialNumber
• BSC/StatusV2, State, Device, Realtime
• Space: AvailableSize / TotalSize (as one progress bar)
• Slots: BSC/NumActiveSlots / BSC/ExpectedSlotCount (as one progress bar)
• Log: LogUsedSize/LogTotalSize (as one progress bar) SystemSize (it would be nice to show it on one row)

it would be also nice to show BSC/SharedWithOs attribute as a label. it's only important when it's true. so, it could be absent otherwise.
