Description

When a user initiates "major" cluster reconfiguration operations, such as Enable NameNode HA, Enable Kerberos, Add Hosts, Add Services, etc, the user forces any user who accesses Ambari Web to be redirected to the wizard.
This unnecessarily restricts what the users can do, and also it is dangerous because multiple users may interact with the wizard (or keep the wizards open and multiple instances can make API calls with side effects, causing failure).
If users different from who initiated the major reconfiguration operation logs in while the operation is still going on, the user should not be force redirected, but instead be able to access the cluster in read-only mode with some indication that "NameNode HA is being enabled", etc (much like what happens when Rolling Upgrade is happening).
