Remove "name" field from Metric Definition

What does this MR do and why?

This is one of several MRs to remove name from metric definitions. See: #411602 (closed)

This MR removes the names from all existing metric definitions.

I used the following script (remove_name.sh) to modify the metric definitions:

for directory in "$@"; do
  for file in "$directory"/*; do
    if [ -f "$file" ]; then
      sed '/^name:/d' "$file" > "$file.tmp"
      mv "$file.tmp" "$file"
    fi
  done
done

To run it: bash remove_name.sh config/metrics/counts_* ee/config/metrics/counts_*

How to set up and validate locally

To validate that all relevant metric definitions has been updated, run grep "name:" config/metrics/counts_*/* ee/config/metrics/counts_*/*.

You can run the same command on master to see the difference.
