IdStory Identity Manager

I take this ticket. For first will be created request and then maybe will be this implemented in extras module.

First implementation exists.

Now is possible define infinite system with configuration properties. Against these system will be made authentication. Example of configuration properties:

idm.sec.extras.security.auth.order10.systemId=addc7c0-086b-44b5-9d0a-8dd265c16553
idm.sec.extras.security.auth.order11.systemId=ea86a399-9b26-4f75-9b3a-d3f0049031ef
idm.sec.extras.security.auth.order12.systemId=eb24ee1e-da69-4e8a-8b7d-8e41691f09e4
idm.sec.extras.security.auth.order13.systemId=e6a8b1e7-d656-47ae-aa2d-1062d1583c1a
idm.sec.extras.security.auth.order14.systemId=ecb6633a-088d-4021-ad56-5c22fb7a2b7f
idm.sec.extras.security.auth.order15.systemId=71fcccb6-5865-48e6-8fba-3d4d963d9f45

Implementation was finished.

• all behavior with authentication against system was moved to new abstract class - AbstractAccAuthenticator,
• throws from authentication was removed - changed old behavior.

• new authenticator - DefaultAccMultipleSystemAuthenticator (SUFFICIENT) (order is after old authenticator),
• low ux desing,
• new configuration class for acc authenticators - AuthenticatorConfiguration,
• new configuration options with acc module prefix - old configuration property still exists.

Documentation missing.

Please Radek could you provide me a feedback? Thank you ❤️

I did test and code review, it works, thx! Code looks nice too (except ... you know :))

Minor review notes:
- AuthenticatorConfiguration - prevent to append configuration property from other constant - use configuration property as one string (configuration property can be found by ctrl-cv from documentation).
- AuthenticatorConfiguration - I like the property uses module prefix now, awesome! Maybe "systemId" can be ranamed to "system" => codeable is supported here.
- AuthenticatorConfiguration - SysSystemDto should be returned instead raw Strings (e.g. RoleConfiguration#getAdminRole) - now all callers has to check and resolve wrong configuration.
- DefaultAccAuthenticator could be deprecated - new DefaultAccMultipleSystemAuthenticator fully cover this feature.
- AbstractAccAuthenticator#161 - comment "Warning: There is silent error. Because one user can has more system and we don't fill log with errors." should be removed now? :)
- DefaultAccMultipleSystemAuthenticator#45 - comment "Before CORE module and after original ACC module. Original authenticator has bigger priority than this authenticator." - the core module is first, then this, old at the end (it's reversed). :)
- DefaultAuthenticatorConfiguration#65 - DEFAULT_AUTH_MAX_SYSTEM_COUNT is "long" - check for null value ca be removed (+ better coverage)

Except the first composable property :D:

• prevent to append configuration property - I little bit changed behavior with append but there must be still two properties,
• "systemId" can be ranamed to "system" - renamed,
• SysSystemDto should be returned - both method in AuthenticatorConfiguration now return SysSystemDto,
• deprecated DefaultAccAuthenticator - the DefaultAccAuthenticator is now deprecated with some information about new usage,
• AbstractAccAuthenticator#161 - comment - comment was removed,
• DefaultAccMultipleSystemAuthenticator#45 - comment the order was little bit changed and comments changed,
• DEFAULT_AUTH_MAX_SYSTEM_COUNT is "long" check for null was removed and now is return directly result form getLong.

Please could you check the result? Thank you :)

Thx! Merged into develop.
