feat: add dependency-check

[kamushadenes]

✍️ Description

For me, it has always been a pain to ensure that a VM or container is only started when another VM or service is up.

Start delays are extremely flaky and inefficient. This script helps solve that.

It's a hookscript that runs on pre-start and waits for all referenced storages to be active. Additionally, it supports tags such as dep_ping_<hostname_or_ip> to wait until a IP is reachable and dep_tcp_<hostname_or_ip>_<port> to wait until a TCP port is open.

Oops, I didn’t saw that, I had opened first in the main repo, let me fix this mess.

Apologies for the delay, busy week @MickLesk

I think someone had force-pushed to main, that's what caused the issue.

Anyway, it's fixed now.
