* filer: allow clearing a bucket read-only flag stuck after quota removal Once s3.bucket.quota.enforce marks a bucket read-only, removing or disabling the quota orphans the flag: enforcement skips buckets with a non-positive quota, and fs.configure merges booleans with OR so -readOnly=false could never turn it off. The only way out was deleting the whole path rule. - s3.bucket.quota -op=remove/disable and the admin server quota update now lift the read-only flag on the bucket's path rule - fs.configure now honors explicitly passed false boolean flags (-readOnly, -fsync, -worm) instead of OR-merging them away * filer: ClearBucketReadOnly reports unchanged when the save fails
