Multi-base with the same bucket name in different storage accounts

For Azure, different storage accounts can have buckets (containers) of the same name. Also storage account is the unit of rate limit cap.

When expressed as base, today we try to match base based on the prefix, and that would mean it can only match 1 bucket but not the others if user defines multiple bases of the same buckets in different storage accounts.

We need the ability to define storage_options as a part of the base definition, so that we can express something like

message BasePath {
  uint32 id = 1;
  optional string name = 2;
  bool is_dataset_root = 3;
  string path = 4;
  map<string, string> storage_options = 5;
}
