[Feature]: Enable JSONPath or alternative to pass backup configuration as CLI Arguments

[ganderaj]

Is your feature request related to a problem? Please describe.

We are developing an automation to trigger backup creation for different Milvus DBs across our PRD and DEV Milvus environments on a scheduled basis.

Thinking is, we maintain a single copy of milvus-backup and corresponding backup config and pass backup arguments like S3 Bucket, backup and log path as CLI flags. However, tool doesn't support passing backup configuration forcing us to update backup.yaml every time or having to maintain multiple such config files.

Describe the solution you'd like.

It'd help us if tool provides support for passing backup configuration dynamically. Think in the lines of how you'd pass "values" for helm charts via CLI.

Ideally, a user should be able to trigger backup using below command

./milvus-backup create -n <backup_name> -d <DB_name> --set minio.backupBucketName=<Bucket_name> --set log.file.rootpath=</PATH/TO/backup-$(date +%y%m%d%H%M)>

Describe an alternate solution.

Above is laid out keeping helm into consideration.

Alternate solution would be like that of K8s, using JSONPath.

Anything else? (Additional Context)

@ganderaj Hi, it is a reasonable suggestion. Contribution is welcomed. We can put it into our roadmap, but it won't be done very soon
