IdStory Identity Manager

almost completed frontend
todo: do not run validate() if isNew()
questionmark - explaining situation

added info message ( question mark not added - there isn't localization)
fixed assertNotNull -> dont call method if component is new

please look on functionality, I added aditional info into new alert level info, so look if its ok.

I did review. Basically works, but I found some issues:

• SysSystemMappingController - Method validate is not secured (@PreAuthorize("hasAuthority('" + AccGroupPermission.SYSTEM_READ + "')")).
• Test (on BE) for SysSystemMappingService.validate missing.
• Design:
  • Warning message move up (under main title).
  • Use span 12.
  • Merge the warning and info message to only one.
• JavaDoc is "hard coded" for validate missing identifier only. We want the universal validation.
• Method on FE: "showMissingIdentifier" is "hard coded" for validate missing identifier only. We want the universal validation.
• Method "showMissingIdentifier" should be "private", use prefix "_".
• Description and author is missing in "ValidationMessageSystemMapping".
• Error code "SYSTEM_MAPPING_VALIDATION" is not translated. Look to the message history.
• Show validation message dependent on the exception parameter not by exception name (ValidationMessageSystemMapping).
• FE: check on empty response should be 204 not 200.
• SysSystemMappingController - validate method should be return empty response (204).
• Use "Basic.Col" instead "<div col-col-lg-6".
• Beware on code formating:
  

  <div className="col-lg-6 no-border last">
  <ValidationMessageSystemMapping error={validationError} />
  </div>
  

resolving isues from feedback,
completed another validation (Sync mapping for contracts - must exist some mapped attribute with "entityAttribute=true" and "idmPropertyName=identity")

todo:
Error code "SYSTEM_MAPPING_VALIDATION" is not translated. Look to the message history.

issues from feedback resolved, error message localizated, but idm looks into core localization
please look into that and my implemented validation.

commit:
https://github.com/bcvsolutions/CzechIdMng/commit/f5aa40cfcdb8fcee68892d573aa17d015e1487ee

Issues:

• DefaultSysSystemMappingService.validate : * Validation for missing owner must works only for contract mapping, not for all! * "identity" string should be a constant. * Variable "isError" is implemented as noError ... it is confusing. This variable is not global for all validations but only for every validation. * ValidationMessageSystemMapping - should be more dynamic. It is not necessary have dependency for every validation keys. * Localization of validation messages can be split to info and message part.

so I resolved issues from last time and I hope, you can write feedback, please.

I tested it and did review. Works correctly.
