Currently odh-dashboard offers no option to use "secure: false" connection for object storage connection, so the only way to use an insecure "http" connection for your object storage is to go in the backend and update the dspa manually. We should infer this scheme if it's not provided, this way dashboard does not need to provide a field for this.

Acceptance criteria:
Infer "secure" field in dspa if it is not provided (consider removing it entirely but if this api change results in a lot of overhead go with former option).
