Ignore non ascii chars that cant be encoded for prints

[GuyCarmy]

If there is a non ascii char, the plugin breaks with the error below and fails the rundeck job. this fix will skip the print of the char, but probably most of the log will still be usable and its better than current behaviour.

in my case it was the char µ, but it can happen with other chars too.

  File "/var/lib/rundeck/libext/cache/kubernetes-plugin-2.0.5-SNAPSHOT/job-wait.py", line 148, in <module>
    main()
  File "/var/lib/rundeck/libext/cache/kubernetes-plugin-2.0.5-SNAPSHOT/job-wait.py", line 144, in main
    wait()
  File "/var/lib/rundeck/libext/cache/kubernetes-plugin-2.0.5-SNAPSHOT/job-wait.py", line 111, in wait
    print(line)
