[Bug]: IndexNode do not support MINIO_ACCESS_KEY Environment variable

[zwd1208]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I use MINIO_ACCESS_KEY and MINIO_SECRET_KEY environment variables to configure minio for indexnode，but the indexnode logs shows it still use the config file, so indexnode finally can't access the minio

The following shows the log:

Expected Behavior

IndexNode should support read the minio access key and secret from environment variables

env:
- name: MINIO_ACCESS_KEY
  valueFrom:
    secretKeyRef:
      key: access-key
      name: my-release-minio
- name: MINIO_SECRET_KEY
  valueFrom:
    secretKeyRef:
      key: secret-key
      name: my-release-minio

Environment

- Milvus version: v2.0.0-rc6-20210910-020f109
- Deployment mode(standalone or cluster): cluster
