Enhancement: Secrets management

[Brukkil]

Is your feature request related to a problem? Please describe. The problem is that I need to update the secret each time when I add a new monitor that will use it instead of setting some inherited settings for it

Describe the solution you'd like Create properties for secrets that will allow monitors to use them by some rules instead of manually adjusting permissions. Secrets can sometimes be project-wide because only permitted users are present at the project. Maybe create some permissions set for secrets like assigning groups of users that can use it or checkbox "is projectwide?"
