infamy: Always send logs from DUTs to remote syslog in tests

[mattiaswal]

Description

When tests fail in the CI it is often impossible to debug it after the run, to solve this i suggest to always send the syslog as remote syslog

Store the logs per test and per DUT, to be able to be able to trace errors from CI.

1. test-config always setup a syslog to the test PC (test container) over the mgmt interface (IPv6)
2. Test runs
3. Infamy "collect" and package the logs
4. Repeat

Example content:

logs/
   test1/
      dut1/
         kern.log
         messages
         syslog
      dut2/
         kern.log
         messages
         syslog
      dut3/
         kern.log
         messages
         syslog
   test2/
      dut1/
         kern.log
         messages
         syslog

then compress it to logs.tar.gz, if running in CI, publish it as an artifact.
