URL: https://github.com/apache/knox/pull/1243
[KNOX-3332](https://issues.apache.org/jira/browse/KNOX-3332) - Add listeners
on gateway config changes for observers
## What changes were proposed in this pull request?
- Adds an observer pattern so clients are notified if gateway config changes.
- Knox LDAP Server Manager reloads the LDAP configs if there are changes and
restart the LDAP service.
## How was this patch tested?
Unit tests
Manual test:
Started a local Knox and LDAP instance. Changed the knoxsso ldap port to
33390 and tried to login into the homepage which failed. Updated the
gateway-reloadable.xml with the new port 33395 and I was able to log into the
homepage.
