Test-specific helpers in storage-plus

[shanev]

mod.rs in storage-plus/src/indexes contains what appears to be test helpers:

pub fn index_string(data: &str) -> Vec<u8> {
    data.as_bytes().to_vec()
}

pub fn index_tuple(name: &str, age: u32) -> (Vec<u8>, u32) {
    (index_string(name), age)
}

pub fn index_triple(name: &str, age: u32, pk: Vec<u8>) -> (Vec<u8>, u32, Vec<u8>) {
    (index_string(name), age, pk)
}

pub fn index_string_tuple(data1: &str, data2: &str) -> (Vec<u8>, Vec<u8>) {
    (index_string(data1), index_string(data2))
}

Maybe the test-specific parameters like age could use better names? Or maybe this code doesn't belong here?

Yes, these must be defined in the test section.
