[FEATURE] Merge the two watchdog script functionalities into one script

[proditis]

We currently have two python scripts

• watchdog-action.py: which runs from the VPN server and when the event is finished it runs a script
• watchdoger: which runs from the database and when the event is finished it performs an apiNotification HTTP request to the wsserver broadcast endpoint.

Merge those two scripts into one and make the two distinct operations a bit more configurable and functional through command line arguments instead.
