Adding healthchecks.io alerter plus some other stuff

[filak]

Firstly thank you for a great project !

I needed to implement push notifications to https://healthchecks.io/ using their Pinging API

• this has been done in healthchecks.py alerter - a unittest

I have also dived into some other features - not breaking any compatibility hopefully. Sorry for the fat PR - it just happend.

Major:

• network.py has been updated to support also HEAD and POST requests with GET as default - test_network_new.py updated
• full support for enable option in Monitors, Alerters and Loggers - no loading of items with enabled=false
• monitor.group option can have multiple values - same as groups option
• the docs have been updated accordingly

Minor:

• telegram.py - added more logging
• some small docs updates
• I definitely forgot something - will try to update this later...

I have run flake8, black and finally tox - with only:

envlist=py310,py311,py312

I have got the same results as with the current develop branch:

The last two might be some Windows issues.
