# Ticket
https://jira.appcelerator.org/browse/CLOUDSRV-4204

# Description
ACS will upgrade mongo ruby driver, so mongoid need to make some related changes.
@baobeimm , @ins429 
if we pass all options to mongo db ruby driver 1.11.1 without any filtering, it actually work, just when startup acs and dealyed job service will report some warnings: 


host is not a valid option for Mongo::MongoClient
identity_map_enabled is not a valid option for Mongo::MongoClient
autocreate_indexes is not a valid option for Mongo::MongoClient
max_retries_on_connection_failure is not a valid option for Mongo::MongoClient
databases is not a valid option for Mongo::MongoClient
host is not a valid option for Mongo::MongoClient
max_retries_on_connection_failure is not a valid option for Mongo::MongoClient
host is not a valid option for Mongo::MongoClient
max_retries_on_connection_failure is not a valid option for Mongo::MongoClient
host is not a valid option for Mongo::MongoClient
max_retries_on_connection_failure is not a valid option for Mongo::MongoClient

do we need to care for it?
if not, i will not care for these and will not add the code to filter out those options.
