rhc-worker-playbook has implemented progress reporting via while loop checking if thread is allive, in given response interval it sends update message to dispatcher with updated stdout of the script.

Goal: 

• Implement the progress reporting in rhc-worker-script in similar way as in rhc-worker-playbook

Unanswered questions:

• how is the infrastructure going to work? Is it enough to send message to dispatcher with progress or is this going to be special 'channel' for streaming the progress?
• See discussion here

Format of progress showed in the UI is dependent on what rhc-worker-script is able to send:

• Time based - every N seconds send still running message -  'is alive', period based on worker config
• Chunk based - sent messages with stdout/log of the script progress
  • Maybe more of a combination, sent time based chunks of collected stdout 

First draft of worker progress reporting is being done in https://github.com/oamg/rhc-worker-script/pull/100

Acceptance Criteria:

• UI shows message about progress of the script execution
