## Should RabbitMQ node name be computed from the pod's hostname or IP address?
## IP addresses are not stable, so using [stable] hostnames is recommended when possible.
## Set to "hostname" to use pod hostnames.
## When this value is changed, so should the variable used to set the RABBITMQ_NODENAME
## environment variable.

## How often should node cleanup checks run?
