Extend Geo Node Status with information in replication slots
Exposes a new model PgReplicationSlot
that can query information on PostgreSQL replication slots.
The number of used/unused/total slots can be queried, as well as the number of bytes that, overall, the replication slots are reserving in WAL (indicating there could potentially be a problem).
These values are also added to the GeoNodeStatus
object.
Are there points in the code the reviewer needs to double check?
