allow renaming IntoParams field names

[fluxxu]

Use case:

#[derive(Debug, Deserialize, ToSchema, IntoParams)]
pub struct GetInventorySupplyInput {
  pub warehouse_id: String,
  #[param(rename = "sku_list[]")]
  pub sku_list: Option<Vec<String>>,
}

Without the rename, sku_list is serialized as sku_list=1&sku_list=2, but to use with axum::Query we need sku_list[]=1&sku_list[]=2

much needed please add this in a new version - the fork is working!

i need it for renaming 'type' to something else!

#[derive(Debug, Deserialize, IntoParams)]
#[into_params(parameter_in = Query)]
pub struct SearchParams {
    #[param(style = Form, example = "FOOD")]
    query: Option<String>,
    #[param(rename = "type")]
    stype: Option<String>,
    exchange: Option<String>,
    limit: Option<i32>,
}

For these few recent days, I haven't had a time to do much regarding this project. I have had my hands full of other things explained a bit here: #276.

I can add this to the master, but I will not create a release before this feature has been rewritten with serde support #313 thus the rename will then be only temporarily within param(rename = ...) and will be removed when the support is written for serde(rename = ...).

This is pretty okay.

Though it is missing docs and tests. But since this will be only a temporary functionality those can be omitted I suppose. The support should be implemented with serde as described here:
#309 (comment) and here: #313
