Mock LDAP users and groups

[LongLiveCHIEF]

Mock up some ldif files to add ldap groups and users to the test ldap server.

• create a ldif template
• create an ldif for ~10 ldap groups, each containing 10-100 users per group
• dynamically generate random names to populate entries into the ldif files
• create docker exec command to run ldapadd that takes an ldif file
• create script to add ldif entries using ldapadd
