While fail-fast and best-effort make for good
categories at the extreme ends of error handling,
we keep finding outselves wanting to operate
in a middle ground. This change introduces a new
error handling category: FailAfterRecovery. This
option tells corso to complete as much of its
process as it can, even if it recovers from errors.
But at the end of processing, if it recovered from
any errors, an error is returned for the operation.
This behavior is the new failure handling default,
instead of failFast.
