[Orchestrator] - Evolution of configuration file and classes using the organization group definitions

Currently those two lines within fusiondirectory orchestrator : ORCHESTRATOR_TOKEN_BRANCH="ou=orchestrator,ou=tokens,dc=example,dc=com" ORCHESTRATOR_ACCOUNT_BRANCH="ou=dsa,dc=example,dc=com"

It is not required to have them as they can be found within LDAP itself under the configuration of fusiondirectory. They are now defined over there.

We have to change some orchestrator classes as well as its configuration file.

Integrator will be the one being updated to actually retrieve the fusiondirectory configuration.
