liorbond c24c439728 fix: proper error when parsing telemetry configuration (#12981) ...

When parsing `telemetry.global-labels` config the code assumes that the type will be an array.  I saw an issue where someone edited the configuration in the wrong way and got the following error:
![photo_2022-08-21_08-02-21](https://user-images.githubusercontent.com/22855163/185793842-c5759a54-1860-4dd1-bdb4-b94f4dab3c16.jpg)
Instead, I suggest here to print a proper error log to indicate what the issue is.
