[RFE] Redis authentication

[andreasgerstmayr]

Should we provide some means for authentication for the PCP Redis datasource?

I'm not sure however which auth backend to use

• redis doesn't support user authentication afaics [1] (just one single password, but not multiple user accounts)
• should pmproxy connecting to PMCD for authentication? but, except for authentication, there is no dependency from pmproxy on pmcd otherwise at the moment

Sounds like a good idea.

BTW, this is an area that has changed in Redis v6, see: https://redis.io/topics/acl - per-user authentication is now an option.

I don't think pmproxy should connect to PMCD for authentication - if it needs that (it does, we also have a long-standing RFE for pmproxy ACLs), it can do it directly using the same libpcp functionality that pmcd uses.

Great idea. imho that's the way to go - using the same auth backend for pmapi and pmseries is certainly what I as a user would expect.
