Feature Request: Change monitoring type and url

**Is your feature request related to a problem? Please describe.**
Currently it is not possible to change the monitoring type and URL after a monitor is created.

**Describe the solution you'd like**
The Configure menu is already there, it would be nice if it is possible to set a different URL, change the monitoring type and change from HTTPS to HTTP for example.

**Describe alternatives you've considered**
Now the monitor has to be deleted and recreated, causing you to lose the history.

**Additional context**
An internally used url could switch from HTTP to HTTPS. Right now you would need to create a new monitor even though you are monitoring the same service and would like to keep the history.
