What happened: Deploy external-dns latest through helm chart.
Problem: External DNS is not increasing the following metrics counter when there is a problem while registering new hosts

What you expected to happen:
I am expecting to see the following metric reporting a value distinct than 0

How to reproduce it (as minimally and precisely as possible):

Forcing some error test case:

• Preparing our Azure env to not have enough credentials clearance to validate a new entry host.
• See how external-dns is throwing some errors.
