When we try to set uptime/downtime/init on a server testcase we report a wrong error message

[davvore33]

...
warp17> add tests server udp port 1 test-case-id 0 src 20.0.0.2 20.0.0.2 sport 2 2
warp17> set tests timeouts port 1 test-case-id 0 init 0
ERROR: Update not supported for client/multicast-src test type!
ERROR: Failed updating test case 0 config on port 1

Timeouts are not supported on server tests which means that the error its self is an expected behavior but the message is definitively misleading, this has to be fixed before any next release
