IdStory Identity Manager

Implemented. If 'Missing entity', 'linked' and 'unlinked' actions are sets to IGNORE, then only missing accounts action will be performed. No logs will be made for this three ignored actions.

I made performance testing for AD users (4k). Before the modifications, it took a reconciliation where all actions were set to 'Ignore' 4:06 after 3:45.

Skip logging is implemented, but is needed to add posibility to enable / disable logging instead of skip every time.

Feature moved to standalone branch, where configuration will be implemented (e.g. by new action type):
https://github.com/bcvsolutions/CzechIdMng/tree/vsvanda/2949-sync-skip-log-delete-reconcilation

We decided to go with a new action type.

The basic implementation is finished, I still need to write tests and update documentation.

Implemented.
