detect minio image based on the kurl or existing instance

[jala-dx]

What type of PR is this?

type::bug

What this PR does / why we need it:

We cannot really run Node() API unless the kotsadm has cluster wide privileges

Hence added the given below logic to detect the instance type first and accordingly detect the MinIO image

   In existing install with limited RBAC, kotsadm does not have previliges to run Nodes() API.
   If it is a kurl instance, then use search logic to find the best minio image.
   If it is not a kurl instance, return the static image name present in the bundle.
