Server error when MINIO_KMS_SECRET_KEY set on Encryption page

[cesnietor]

In Web UI, when configuring minio setting only the MINIO_KMS_SECRET_KEY, the Encryption section tries to perform /metrics, /apis and /version API requests but since the static key has no version nor metrics nor list apis, they return 500 error.

Expected Behavior

No error

Current Behavior

Possible Solution

In server add api to validate if MINIO_KMS_SECRET_KEY is set, if so don't enable the APIs and Metrics section and not perform the /metrics, /apis nor /version requests.

Steps to Reproduce (for bugs)

1. export MINIO_KMS_SECRET_KEY=my-minio-key:OSMM+vkKUTCvQs9YL/CVMIMt43HFhkUpqJxTmGl6rYw=

2. Run MinIO like

MINIO_STS_DURATION=17m ./minio server ~/Data

3. Go to Monitoring/Encryption (Error happens here.)
