This was vadimsh's idea originally: https://codereview.chromium.org/1365583002/diff/40001/infra/services/service_manager/__main__.py#newcode28

I don't have an opinion one way or the other.

Cloudtail is used in two ways:

1. By service_manager.
2. As a standalone tool (hooked up to stuff via puppet configs).

In case (1) it makes sense to bundle it with infra_python, where service_manager is. Otherwise infra_python would have to know where cloudtail is installed, and will become less self-contained. Currently it is possible to "atomically" update service_manager and cloudtail version it is uses.

In case (2) cloudtail is installed in /opt/infra-tools and used from there.

tl;dr /opt/infra-python/go/bin/cloudtail is private copy of cloudtail and must not be used outside of infra_python.

Is this resolved then?

Yep, this can be wont-fix.
