Accessing a public Concourse feed

[professor]

We have a public concourse feed. There is no need to require a feed username or password.

In looking at the code, it looks like one does not need to set a username or password, neither is sent in lib/ci_polling_strategy.rb#L20

Here's the url:
https://ci.orca.pivotalci.info/api/v1/teams/main/pipelines/gporca/jobs/gpdb_icg_with_orca/builds

Yet, I get a 401 response from the pulse backend with "authorization failed" -- this appears to be a generic error message for any issue.

Maybe the concourse_authenticator.rb code needs the same conditional?
