Querying snapshots by Volume Name

[jwatson-gcu]

NOTE: This behavior is observed on the master branch as of Aug 5, 2021.

I found an issue when querying for snapshots by Volume Name when the volume name contains characters unsafe for URL's. In the event that a volume name contains something like :, which is not url safe, the SDK will convert the request to an advanced search.

This advanced search request is rejected by the SAN.

Here is an example of the code snip-it:

	params := &param.GetParams{
		Filter: &param.SearchFilter{
			Criteria: []*param.SearchFilter{
				{FieldName: &nimbleos.SnapshotFields.VolName, Operator: param.EQUALS.String(), Value: *vol.Name},
				{FieldName: &nimbleos.SnapshotFields.IsManuallyManaged, Operator: param.EQUALS.String(), Value: "true"},
			},
		},
	}
	snaps, err := service.GetSnapshotService().GetSnapshots(params)

Here is the REST API debug log:
