fixes#139
There are other potential long term solutions listed [here](https://github.com/TrueLayer/reqwest-middleware/issues/139#issuecomment-2045946644)
> I didn't put much thought into it. Internally there used to be a `Box<[Arc<dyn Middleware>]>` which is cloned about quite often.

> Because of all the cloning, I decided to flip it to be `Arc<Box>` instead of `Box<Arc>`.
>
> I see three solutions here.
>
> 1. The one I'd lean towards is `Arc<Arc>` even if it's a bit silly, but prevents extra unnecessary allocations on each request.
> 2. An alternative is to implement Middleware for Arc and then you can use the regular with(...) api. This would mean there's an extra box around your middleware
> 3. Revert this particular change
In the short term, I think it's best to go with option 3. This will unblock the next release. We can consider the other options for future releasees
* update reqwest and http crates
remove task_local_extensions
* remove older opentelemetry packages
* remove more legacy and add new otel
* attempt to make features additive
* features are additive
* delete commented out code
* build split
* docs
* more uniform with reqwest::Client
* remove arcs
* slight optimisation
* update readmes
* update changelog
* Add a generic function to the middleware struct for the `Retryable` decision.
The generic function can be used to define custom behaviour to decide whether to retry a request or not.
By default, this function is `Retryable::from_reqwest_response` which is the same as it was before.
* Add a way to create custom retry policies.
A RetryStrategy will dictate what decision will be made based on the result of the sent request.
* Add RetryableStrategy in the `RetryTransientMiddleware` struct instead of the seperate functions
* Add constructor to create a `RetryTransientMiddleware` with a custom `RetryableStrategy`
* Run `cargo fmt`
* Add example code to the `RetryableStrategy` struct
* Run `cargo fmt`
* Updated changelog
* use a trait
* docs
* include latest changes

Addresses an issue where the Http version of a request cannot be changed when using reqwest_middleware
