Force Refresh of credentials inside of STSCredentialProvider cache

### Describe the feature

include a public method for STSCredentialProvider that will forcefully refresh the sessionCache when called

### Use Case

Credentials inside of session cache can become invalid due to a role being deleted and recreated causing `InvalidClientTokenId`, this will continue till new creds are fetched which can take up to 12 hours depending on configuration and in the mean time the client using the provider will be in-operational. Calling the new method will allow for an almost immediate recovery time after catching the error

loose example of recovery

```
try{ client call }
catch(InvalidClientTokenId e){
client.serviceClientConfiguration().credentialsProvider().asInstanceOf[StsAssumeRoleCredentialsProvider].refreshCredentials()
}
```

### Proposed Solution

### StsCredentialsProvider
```
public void refreshCredentials(){
sessionCache.forceRefreshCache();
}
```
### CachedSupplier

```
public void forceRefreshCache() {
try {
boolean lockAcquired = refreshLock.tryLock(BLOCKING_REFRESH_MAX_WAIT.getSeconds(), TimeUnit.SECONDS);

try {
log.debug(() -> "(" + cachedValueName + ") Refreshing cached value.");

// It wasn't, call the supplier to update it.

if (prefetchStrategyInitialized.compareAndSet(false, true)) {
prefetchStrategy.initializeCachedSupplier(this);
}

try {
RefreshResult cachedValue = handleFetchedSuccess(prefetchStrategy.fetch(valueSupplier));
this.cachedValue = cachedValue;
log.debug(() -> "(" + cachedValueName + ") Successfully refreshed cached value. "
+ "Next Prefetch Time: " + cachedValue.prefetchTime() + ". "
+ "Next Stale Time: " + cachedValue.staleTime());
} catch (RuntimeException t) {
cachedValue = handleFetchFailure(t);
}
} finally {
if (lockAcquired) {
refreshLock.unlock();
}
}
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
throw new IllegalStateException("Interrupted waiting to refresh a cached value.", e);
}
}
```

Inizia con StsCredentialsProvider e CachedSupplier, quindi esamina il comportamento esistente di aggiornamento e blocco della cache di sessione. Aggiungi il punto di ingresso pubblico richiesto per l'aggiornamento e assicurati che la cache venga aggiornata forzatamente, gestendo errori e interruzioni in modo coerente; il lavoro è completato quando i chiamanti possono riprendersi rapidamente dopo InvalidClientTokenId.
