Description of problem:

Under normal operation, Candlepin automatically creates /var/cache/candlepin/sync if it's missing. However, if the entire /var/cache/candlepin/ directory is removed (e.g., due to cleanup scripts or admin action), Candlepin fails to recreate it — causing manifest refresh and async operations to fail with a JobExecutionException.

Steps to Reproduce:

1. Remove the Candlepin cache directory:

1. rm -rf /var/cache/candlepin/
    

2. Attempt to refresh a manifest  again.

Actual result:

Manifest refresh fails with:
 
org.candlepin.async.JobExecutionException: Unable to create base dir for sync: /var/cache/candlepin/sync
 
Expected Result:
Candlepin should detect the missing directory and recreate /var/cache/candlepin/ and /var/cache/candlepin/sync with proper permissions automatically.

Business Impact / Additional info:

Breaks critical workflows (e.g., manifest refresh) when /var/cache/candlepin/ is missing.

Relies on a directory that may be deleted or cleaned up, and is not usually monitored or backed up.
