Increase verbosity of triggered build
Displays the URL to the triggered pipeline, so that it can be easily accessed. Moved logic to a ruby script which does the following:
- Disable
before_script
in manual job. We are doing a simple curl, which doesn't need any gems to be installed - Suppress output of
curl
and redirect any possible output to/dev/null
- Print the URL to the triggered pipeline neatly
