npbackup Add healthcheck support and emailing capacities

For those who don't want to play with prometheus, add emailing capacities:

On success
On failure
On too old backups

Those emails should contain the last let's say 1000 lines of logs in case of failure.

Possible to be able to ping an URL (e.g. healthchecks.io) with "/success" added at the end of the URL in case of success and "/failure" added in case of failure?

Sure, that would be fairly easy to do. Actually, healthechecks.io has been (quickly) discussed here https://github.com/netinvent/npbackup/discussions/140

I don't really know that service. Does it take some POST data ? How do you identify which asset pings /success or /failure ?

I would say I could provide 2 URLs, one for success and one for failure, and npbackup calls the success one when there is success and the failure one when there is failure.

@lcswillems Okay, I see, you just need to set an arbitrary UUID given by healthchecks in the URI. Looks straightforward.

Email capabilities are part of current v3.0.3 release. Next release will contain healthchek links. Sorry for the delay. Linked to #75
