Insufficient error message when data preprocessing failed

[Dmitry Tantsur]

Not sure what I was thinking back then, but this is not a good error message:
+----------+----------------------------+
| Field | Value |
+----------+----------------------------+
| error | Data pre-processing failed |
| finished | True |
+----------+----------------------------+

Expected something like:
+----------+----------------------------------------------------------------------------------------------------------+
| Field | Value |
+----------+----------------------------------------------------------------------------------------------------------+
| error | Preprocessing hook ramdisk_error: Ramdisk reported error: The following errors were encountered: |
| | * collector logs failed: 'ascii' codec can't decode byte 0xe2 in position 241: ordinal not in range(128) |
| finished | True |
+----------+----------------------------------------------------------------------------------------------------------+

    Properly report preprocessing errors to a user

    Currently we only return "Data pre-processing failed" and the only option
    to figure out what went wrong is to dive into logs.

    Also fixed error message for unexpected exceptions during pre-processing
    to actually contain some exception information.
