Server compatibility level upgrade with no downtime

Description: This support allows improved availability when migrating new function across a sysplex. To update the serverCompatLevel or backends in a sysplex group without LDAP service outage, a run mode (transition mode) is now added. The LDAP instance can now be started in transition mode and continue to be operational while others are updated and recycled. In transition mode, the server can be started successfully with the updated serverCompatLevel or backends configurations. Transition mode is a temporary work mode that is used during sysplex level configuration updates.
