feat: Adds statistics measurement for compact-throughput (#26754)#26883
Conversation
This PR adds the following as an available `/debug/vars` field.
```
"stats" : { "compact-throughput-usage-percentage" : <percentage used> }
```
This will show the current compaction throughput usage WRT the available limiter tokens as defined by the golang rate limiter.
https://pkg.go.dev/golang.org/x/time/rate#Limiter.Limit
https://pkg.go.dev/golang.org/x/time/rate#Limiter.Tokens
The algorithm for finding our usage is the following
```
percentage = 100 * (1 - (tokens) / limit)
```
(cherry picked from commit 879e34a)
