Intermittent Submission Failures Due to Disk Quota Exceeded

[karatugo]

Description: Submission 665a1272f2bba900017a9f6f failed validation due to exceeded disk quota in the /homes/gwas_lsf directory. See https://github.com/EBISPOT/goci/issues/1341

Proposed Solution: To prevent future occurrences, set up a cron job that regularly cleans up the directory by moving files larger than limit (e.g. 100MB) to the scratch directory.
