Too many metrics requests causing SQL link failure

### Current Behavior

I used a database pool. Can I set a maximum request volume for metrics requests? If there are too many, or can I simply disable this loop update feature

### Steps to Reproduce

1. system update metrics;
2. sql connect timeout;
3.new api request error;

### Expected Behavior

Less metrics requests

### Dependency-Track Version

4.12.x

### Dependency-Track Distribution

### Database Server

### Database Server Version

### Browser

No source files, tests, or entry points are named. Start by tracing the database pool and metrics update loop described in the reproduction, then verify the SQL timeout and subsequent API request behavior. Done means metrics requests are reduced or the loop can be disabled without breaking API requests.
