Description of ManagementRealm should not be part of JBOSS-LOCAL-USER Realm

Book: How to Configure Server Security
Revision: 6bff93b8
Section: 3.1.1.2. Default Elytron Management CLI Authentication

Issue description:
At the end of section 3.1.1.2. Default Elytron Management CLI Authentication there is section "JBOSS-LOCAL-USER Realm" where local security realm is described. Then there is also described ManagementRealm. It looks like ManagementRealm is also related to JBOSS-LOCAL-USER Realm but it is not.

Suggestions for improvement:
Change sentence "The ManagementRealm Elytron security realm is the same realm used ..." to "The ManagementRealm Elytron security realm used in DIGEST-MD5 is the same realm used ..." and move whole this sentence just before "JBOSS-LOCAL-USER Realm" section.
