add tests for JCA workmanager and security inflow using legacy security and elytron security domain

Add test for JCA workmanager and security inflow:

• using legacy security domain
• using Elytron security domain
• mixed scenario where RA is defined with Elytron security domain and WorkManager hasn't enabled Elytron integration (it defaults to legacy security integration) - it's not supported and deployment should fail

JBEAP-9044/WFLY-8204 adds elytron-enabled attribute to workmanager configuration
