Startup of snap.microceph.daemon.service fails with " listen tcp <ip>:7443: bind: cannot assign requested address"

Startup of snap.microceph.daemon.service fails with the following error message:
```
microceph.daemon[1128]: Error: Daemon stopped with error: Daemon failed to start: Failed to listen on https socket: listen tcp x.x.x.x:7443: bind: cannot assign requested address
```

Error is caused by the network (using DHCP as assignment method of IP address to LAN network interface) not being ready when daemon and other microceph services start.

According to /etc/systemd/system/snap.microceph.daemon.service the service startup is done after network.target:
```
[Unit]
# Auto-generated, DO NOT EDIT
Description=Service for snap application microceph.daemon
Requires=snap-microceph-1395.mount
Wants=network.target
After=snap-microceph-1395.mount network.target snapd.apparmor.service
X-Snappy=yes
```

A simply manual restart of the service after the system is booted brings the service up (now that a DHCP address is assigned to the network interface).

Would it be possible to require startup microceph services after "network-online.target" instead of "network.target" ?
