Add a --continue option to ndctl-create-namespaces to allow the creation

The creation loop will be aborted if a failure is encountered at any

Just wondering what is the motivation behind providing this option?
Hi Jane,
See Steve's email here:

Essentially it lets sysadmins create a simple, maximal configuration
without everyone having to script it.
It also gives a touch point to start thinking about parallel namespace
creation. The large advancements in boot time that Alex achieved were
mainly from parallelizing namespace init. With --continue we could
batch the namespace enable calls and kick off a bind thread per
namespace.
Thanks Dan! Sorry I was reading email backwards, just caught up with
the earlier discussions.
With the --continue option, assuming the --size option will be taken if
specified, it would be possible to end up with a large number of small
namespaces
with a simple command that runs for a long while, right? can it be
killed by ctrl-c once the innocent user regrets? :)
thanks,
-jane
