Bug 1018810

+++ This bug was initially created as a clone of Bug #1015194 +++

Description of problem:
After updating the storage node configuration, the UI shows the old values from before the change. This is not a UI specific issue. The same behavior can be found in the CLI. The problem stems from how we perform the resource configuration change. It is being done as a resource operation and not as a configuration update (via ConfigurationManagerBean). The method StorageNodeManagerBean.retrieveConfiguration(Subject, StorageNode) returns the latest values in the database and those values become stale when the resource operation is executed because the change is only made on the physical resource and not updated in the database. 

I think that the config changes should be done as a resource config update. This has two benefits. First, it resolves this issue because the resource config update will update the actual resource as well as the value in the database. Secondly, we have an update trail of the config changes. By applying the change as a resource operation we do not have an easy way to see what past values of the storage node configuration look like.

Version-Release number of selected component (if applicable):


How reproducible:
always

Steps to Reproduce:
1. Go to storage node admin UI
2. Go to storage node details view
3. Change any of the configuration settings and click the Save button

Actual results:
The values prior to the change are displayed

Expected results:
The new values should be displayed

message: [BZ 1015194] - Storage node configuration UI shows stale values - The
         restart is now done in the SLSB layer using the resource
         operation instead of the agent side, because we don't want to
         let the common resource configuration updates to cause the
         restart of the storage node (the restart is done only for those
         config changes that was done using the admin UI).
