SystemTablePersistence - Value too long for character type error

Hello team,

I'm getting the following error when I execute the SystemTablePersistence lambda utility:

ERROR] ProgrammingError: {'S': 'ERROR', 'C': 'XX000', 'M': 'Value too long for character type', 'D': '\n -----------------------------------------------\n error: Value too long for character type\n code: 8001\n context: Value too long for type character(30)\n query: 213818\n location: string.cpp:213\n process: query0_113_213818 [pid=25354]\n -----------------------------------------------\n', 'F': '../src/sys/xen_execute.cpp', 'L': '12414', 'R': 'pg_throw'}

**Solution:**

And the solution is to increase the size of the field "label" in [here ](https://github.com/awslabs/amazon-redshift-utils/blob/8085eeb48036ad236325adfe40c63425dd3cf2f1/src/SystemTablePersistence/lib/history_table_creation.sql#L14)

In my case the values were between 30 to 50 but I made it CHAR(100) for the moment.

Start with src/SystemTablePersistence/lib/history_table_creation.sql at the label field referenced in the report, then trace its use from lib/SystemTablePersistence/snapshot_system_stats.py. Reproduce the SystemTablePersistence snapshot if possible and verify that label values in the reported range are stored without the character-length error.
