[PATCH datacenter-manager v4 20/21] pdm-config: subscriptions: drop unused accessor functions

[Lukas Wagner <l.wagner@proxmox.com>]

Now that the subscription API handlers reach the config through
PdmApplication instead, the free functions built on top of the global
INSTANCE static are unused. Drop them along with the init() call that
used to populate it.
