Allow the exception and error status
strings to be passed in such that other plugins can
make use of this function.
There is a comment in find_resource:
The exception to catch here is dependent on which
client library the manager passed in belongs to.
Eventually this should be pulled from a common set
of client exceptions.
Since I think that is a long ways off, this change will
work now and also work when a common exception is defined
and used.
