Tristan Partin b623fbae0c Cancel PG query if stuck at refreshing configuration (#12717) 
## Problem

While configuring or reconfiguring PG due to PageServer movements, it's
possible PG may get stuck if PageServer is moved around after fetching
the spec from StorageController.

## Summary of changes

To fix this issue, this PR introduces two changes:
1. Fail the PG query directly if the query cannot request configuration
for certain number of times.
2. Introduce a new state `RefreshConfiguration` in compute tools to
differentiate it from `RefreshConfigurationPending`. If compute tool is
already in `RefreshConfiguration` state, then it will not accept new
request configuration requests.

## How is this tested?
Chaos testing.
