Description of problem:

We need to document how to update / change the keystore config or remove it to add another one.

The docs should show to add https realms with a keystore, but not updating/removing: 

/core-service=management/security-realm=ManagementRealmHTTPS/server-identity=ssl:add(...)



Document URL: 

https://access.redhat.com/documentation/en/red-hat-jboss-enterprise-application-platform/version-6.4/how-to-configure-server-security/

Section Number and Name: 

Describe the issue: 

Need to show how to modify / remove after adding.  Users looking at the docs were trying to call add again to update their keystore which lead to :

{
    "outcome" => "failed",
    "failure-description" => "JBAS014803: Duplicate resource [
    (\"core-service\" => \"management\"),
    (\"security-realm\" => \"ManagementRealmHTTPS\"),
    (\"server-identity\" => \"ssl\")
]",
    "rolled-back" => true
