Experiment with proof of concept utoipa axum bindings.
Experiment with axum Router and Handler bindings with utoipa. Bind axum router to the utoipa OpenApi and `#[utoipa::path]` attribute macro. Wip: for axum, find the `State<T>` of the stateful handler to implement correct type for `axum::handler::Handler` trait.
Working bindings with axum and utoipa that handles `#[utoipa::path]` macro merging with with `axum::Router` and `utoipa::openapi::OpenApi`. Missing some documentation, test finalization and parhaps some utility functions. Some polish could be done for the `tags`. Now there is no tags when using `OpenApiRouter` on operations. The `tags` behavior must be unified somehow. Finally write an example app with `OpenApiRouter` to `examples`.

This PR adds a new crate `utoipa-axum` which provides bindings between
`axum` and `utoipa`. It aims to blend as much as possible to the
existing philosophy of axum way of registering handlers.
This commit introduces new `OpenApiRouter` what wraps `OpenApi` and axum
`Router` which provides passthrough implementation for most of the axum
Router methods and collects and combines the `OpenApi` from registered
routes. Routes registred only via `routes!()` macro will get added to
the `OpenApi`.
Also this commit introduces `routes!()` macro which collects axum
handlers annotated with `#[utoipa::path()]` attribute macro to single
paths intance which is then provided to the `OpenApiRouter`.
Example of supported sytanx.
```rust
let user_router: OpenApiRouter = OpenApiRouter::new()
.routes(routes!(search_user))
.routes(routes!(get_user, post_user, delete_user));
```
Fixes #991
