max-attr-len was added recently to constrain overall attr len for testing on crimson/seastore. This is reasonable, but older ceph_test_rados versions do not support this argument. Some possible solutions:
- modify rados task to only pass --max-attr-len if specified in the yaml and update crimson/seastore tests to specify it
- modify upgrade tests to not pass --max-attr-len
- modify rados task to notice ' unknown arg --max-attr-len' string in stderr and rerun without --max-attr-len

The last one above is probably the simplest.
