Description
**Is your feature request related to a problem? Please describe.**
The unstable raft log pins memory that is not tracked anywhere.
We should surface this.
**Describe the solution you'd like**
**Describe alternatives you've considered**
**Additional context**
This was done, in a hacky way, [here](https://github.com/cockroachdb/cockroach/pull/98576/files#diff-6be678e167bfa77014c7061ea7742f3528047fa1d90b892995443a8265300092R776) during an experiment.
