the schema for the attributes
the attribute keys and values
a collection alias, or D-Bus object path of the collection where to store the secret

the secret value
optional cancellation object
whether the storage was successful or not
Store a secret value in the secret service.
The attributes should be a set of key and value string pairs.
If the attributes match a secret item already stored in the collection, then the item will be updated with these new values.
If collection is null, then the default collection will be used. Use constCOLLECTION_SESSION to store the password in the session collection, which doesn't get stored across login sessions.
If service is null, then secret.service.Service.getSync will be called to get the default classService proxy.
