fix: Disable column-statistics during mysqldump command. This option

Browse Source 
was recently enabled by default in mysqldump, but the generation of
histogram statistics fails in devstack during this script's mysqldump
commands. The SQL statement and output of the failure:

mysql> SELECT \
COLUMN_NAME, JSON_EXTRACT(HISTOGRAM, '$."number-of-buckets-specified"') \
FROM information_schema.COLUMN_STATISTICS \
WHERE \
SCHEMA_NAME = 'edxtest' AND \
TABLE_NAME = 'agreements_integritysignature';
ERROR 1109 (42S02): Unknown table 'COLUMN_STATISTICS' in information_schema
