[ClusterLabs] Running several instances of a Corosync/Pacemaker cluster on a node

Is it possible to run several instances of a Corosync/Pacemaker clusters
on a node? Can a node be a member of several clusters, so they could put
resources there? I'm sure it's doable with separate nodes or containers,
but that's not the case.

My case is to separate data-critical resources, like storage or VIPs,
from the complex resources like DB or MQ clusters.

The latter should run with no-quorum-policy=ignore as they know how to
deal with network partitions/split-brain, use own techniques to protect
data and don't want external fencing from a Pacemaker, which
no-quorum-policy/STONITH is.

The former must use STONITH (or a stop policy, if it's only a VIP), as
they don't know how to deal with split-brain, for example.
