num_objs (int): number of objects to create in the container.
num_dkeys (int): number of dkeys to create per object.
num_akeys_single (int): number of DAOS_IOD_SINGLE akeys per dkey.
num_akeys_array (int): number of DAOS_IOD_ARRAY akeys per dkey.
akey_sizes (list): varying akey sizes to iterate.
akey_extents (list): varying number of akey extents to iterate.
Returns:
list: a list of DaosObj created.
