[pve-devel] [PATCH manager] api: ceph: mon: make checking for duplicate addresses more robust

[Fabian Ebner <f.ebner@proxmox.com>]

Because $mon->{addr} might come with a port attached (affects monitors
created with PVE 5.4 as reported in the community forum [0]), or even
be a hostname (according to the code in Ceph/Services.pm). Although
the latter shouldn't happen for configurations created by PVE.

Fixes: 86ed64f9 ("api: ceph: mon: fix handling of IPv6 addresses in assert_mon_prerequisites")
