This adds a `Load` Opt for cio to load a tasks io/fifos without
attaching or starting the copy routines.
It adds the load method in `ctr` by default so that fifos or other IO
are removed from disk on delete methods inbetween command runs. It is
not the default for all task loads for backwards compat. and a user may
want to keep io around to reuse or if log files are used.
Fixes#2421
