John Spray d22dce2e31 pageserver: shut down idle walredo processes (#5877) ...

The longer a pageserver runs, the more walredo processes it accumulates
from tenants that are touched intermittently (e.g. by availability
checks). This can lead to getting OOM killed.

Changes:
- Add an Instant recording the last use of the walredo process for a
tenant
- After compaction iteration in the background task, check for idleness
and stop the walredo process if idle for more than 10x compaction
period.
