Description

The following commit:
3f2b0939f8 LU-8323 tests: Fix interop for set_hostid
breaks the testing in setup where the mixed clients installed (2.12 + 2.7, main client is 2.12): llmount.sh fails on formatall()->do_rpc_nodes "$(comma_list $(remote_nodes_list))" set_hostid because 2.7 clients does not have set_hostid()
