[PR #9275/adb4b3c8 backport][stable-10] Add module ldap inc (#9480)

Add module ldap inc (#9275)

* Add module ldap_inc

This module adds the ‘modify-increment’ capability corresponding to the extension implemented by OpenLdap described in RFC-4525. It can be used to increment an integer attribute and read it atomically. It is an help for posix userId definition while relying only on the directory server.
