Publish indy pipelines' logs to Nexus

As ry pointed in out indy jobs we need to use the standard macros (used by all jenkins jobs)  to publish the logs to nexus because logs are not kept for a long on Hyperledger Jenkins server.

Examples and snippets that Ry suggest to start with:

 publishers:
 - lf-infra-publish

 builders:
 - verify-commit-message
 

 publishers:
 - lf-infra-publish
 - archive-artifacts:
 artifacts: '.tox/**/*.log'
