Refresh metrics needs PORTFOLIO_MANAGEMENT permission

### Current Behavior

The permission `PORTFOLIO_MANAGEMENT` is required to refresh metrics (https://github.com/DependencyTrack/dependency-track/blob/d8464427fa993404961563e97bdd5f2564b4f7ce/src/main/java/org/dependencytrack/resources/v1/MetricsResource.java#L245-L258)

### Steps to Reproduce

1. make a HTTP GET request to the corresponding URL

### Expected Behavior

Access to this resource should probably require less permission.

`VULNERABILITY_ANALYSIS` could correspond to a use case where the user has the right to perform vulnerability analysis (or maybe `VIEW_PORTFOLIO`?)
