Thinking about that, ClusterLabs may be considered a brand established
well enough for "clusterlabs" provider to work better than anything
general such as previously proposed "core".  Also, it's not expected
there will be more RA-centered projects under this umbrella than
resource-agents (pacemaker deserves to be a provider on its own),
so it would be pretty unambiguous pointer.

And for new, not well-tested agents within resource-agents, there could
also be a provider schema akin to "clusterlabs-staging" introduced.
