Test End-to-end V1.0, testing Bottin's behavior

Tests wrote in golang without framework Testing on the Bottin's behavior

Tests made:
- crated random Users and Group - LDAP ADD
- check the match between Consul's data and Test's data- LDAP
  Search
- modify attributes and check them -
  LDAP Modify
