cleanup script often does not succeed in removing files with unicode
characters.
[common_test] Add documentation for ct_netconfc:send and send_rpc
[ct_netconfc] Allow multiple elements inside filter in create_subscription

ct_netconfc:create_subscription only allows one XML element inside the

number of elements inside the filter, so this is now corrected.
