metric: add KMS-related metrics (#15258)

This commit adds a minimal set of KMS-related metrics:
```
 # HELP minio_cluster_kms_online Reports whether the KMS is online (1) or offline (0)
 # TYPE minio_cluster_kms_online gauge
 minio_cluster_kms_online{server="127.0.0.1:9000"} 1
 # HELP minio_cluster_kms_request_error Number of KMS requests that failed with a well-defined error
 # TYPE minio_cluster_kms_request_error counter
 minio_cluster_kms_request_error{server="127.0.0.1:9000"} 16790
 # HELP minio_cluster_kms_request_success Number of KMS requests that succeeded
 # TYPE minio_cluster_kms_request_success counter
 minio_cluster_kms_request_success{server="127.0.0.1:9000"} 348031
```

Currently, we report whether the KMS is available and how many requests
succeeded/failed. However, KES exposes much more metrics that can be
exposed if necessary. See: https://pkg.go.dev/github.com/minio/kes#Metric
