IdStory Identity Manager

I made first version of generating an mapped attributes by schema attributes.

It is realize by processor (SystemMappingIdentityAutoAttributesProcessor) on create system-mapping. Implemented are only basic fields from a identity.
This processor is used only if event contains enable property. This is necessary for ensure backward compatibility (because VS and tests).

Tests were created too.

This feature is awesome, I did test and code review.

I found some issues:
- seccurity is missing in overriden SysSystemMappingController#post and SysSystemMappingController#postDto can be overriden instead (benefit - less code + just event propagation without response)

Some notes only (can be implemented optionally):
- SysSystemMappingService#ENABLE_AUTOMATIC_CREATION_OF_MAPPING - 'core:' or 'idm:' prefix and format can be used (see EntityEvent properties).
- name catalogues can be moved to static string array constants in processor (e.g CATALOGUE_PHONE = new String{"phone", "mobile" ...}) - it will be visible at the first sight (configuration is not necessary i hope so, but this catalogue will be improved in future after project feedback maybe).

I made some improvements (you have a good eye on the security issues):
