misc(metrics)!: split global attributes into two (celestiaorg#2546)

## Overview

Currently there is only one global attribute, that build by
concatenating both exported attributes:

```
"job" = "Bridge/robusta-11rc9/12D3KooWAEQUSJh7aJFq7Cw1mP4VWnqfHtHwwwnsXHFhpQ2DMn7j"
```

`Breaking`, because this PR is breaking metrics compatibility.
