Fix exception message of CoraidESMConfigureError

Since 'message' is the same name as the second argument to the
constructor of CinderException, 'message="Oorah"' is not a keyword
argument.

Therefore, "message = _('ESM configure request failed: %(message)s.')"
doesn't work correctly.

Then, remove the redundant period.
