Description of problem:
Schedule remote command action on multiple systems using SSM and when it fails on some of them, use "Reschedule" button on individual server page and notice that it reschedules the action on all of the servers from initial set.


Version-Release number of selected component (if applicable):
spacewalk-java-2.3.8-112.el6sat.noarch


How reproducible:
always


Steps to Reproduce:
1. Register 2 clients and add "Provisioning" add on entitlements to them
2. Make sure clients have remote actions enabled
   # rhn-actions-control --enable-run
3. Using SSM, schedule remote command action which fails on one of
   systems, like:
   # hostname | grep 'unique_part_of_hostname_of_one_system'
4. Run `rhn_check -vv` on both systems so the action is picked:
   [...]
   D: do_call script.run(105670, {'username': 'root', 'groupname': 'root', 'now': '2015-09-14 01:23:25', 'timeout': 600, 'script': '#!/bin/sh\nhostname | grep unique_part_of_hostname_of_one_system'}){'cache_only': None}
   [...]
   D: Sending back response(...
   [...]
5. Go to Systems -> system where it failed -> Events -> History -> failed
   action and click "Reschedule" button


Actual results:
Notice that action is rescheduled on the system it passed as well.


Expected results:
Maybe there should be way how to reschedule only failing systems, or we should be more clear that this button (which is tied to individual system) reschedules action on *all* systems.
