Closes https://github.com/paritytech/jsonrpsee/issues/448

This PR adds an implementation for `SubscriptionClient` to the `HttpClient` struct, which makes it possible for http clients to use macro-generated RPC servers. If an http client tries to set up a subscription it will fail with a `HttpNotImplemented` error.

* request ID as RAII guard

* clippify

* fmt

* address grumbles: naming

`RequestIdGuard` -> `RequestIdManager`
`RequestId` -> `RequestIdGuard`

* Update tokio-rustls requirement from 0.22 to 0.23

Updates the requirements on [tokio-rustls](https://github.com/tokio-rs/tls) to permit the latest version.

* register_*_method Into<Error>

* clippy

* replace generic errors with anyhow::Error

* fix nits

* example that anyhow::Error in register_method works

* CallError: add missing From impl

* [types]: add helper methods for Error types

The rationale is to make it possible for users to either use anyhow::Error or use the helper methods.

* fmt

* Revert "register_*_method Into<Error>"

This reverts commit 33b4fa28730b72647ba150659d3c0ab1937e524a.

* add better comment

* fix nit

* Sniff the first byte to glean if the incoming request is a single or batch request

This works around the serde limitations around `untagged` enums and `RawValue`.

* fmt

* For http server, check first byte before allocating space for the body

Also, rework the way we return errors: prefer JSON-RPC errors according to spec (application/json) wherever sensible.

* Review feedback

* Don't assume there is a first byte to read

* ty clipyp

* Review concerns

* Cleanup

* Impose a timeout on all requests

Variant of #367

This PR takes a more opinionated stance than #367, where timeouts are optional. In this PR I suggest we make a all requests use a timeout and only let users choose the length.

* [types]: allow `data` field in jsonrpc error obj.

* fmt

* revert change to make fail

* remove redundant test

* [types]: bring back `data` and `message` in error.

Basically deducing the error message from server defined error doesn't work
and we should not strip out this information from to user which might be useful.

* remove boiler plate code

* [types]: impl From<ErrorCode> for JsonRpcError

* address grumbles

* remove more boiler plate

I went over all the atomic operations and realised I could not convince myself that all uses of `Relaxed` were ok, so better safe than sorry: let's switch to `SeqCst`.

* Use a constant to express max request body size
Consistently use u32 in all crates

* [client]: batch request generic response

* wait with impl

* [ws client]: add template for batch requests

* remove jsonvalue

* naive impl

* fix make it work,

The implemenation is quite inefficient because the responses might be unordered.
Currently, a "digest" of a BTreeSet is stored to sort the requestIDs
and don't have to try all combinations of requestIDs in the response.

* fix nits

* error handling

* fix nits

* more nits

* use error msg pattern

* add batch requests to client trait

Keep it simple by require `Vec<(Method, Params)>` could be improved.

* address review comments: use swap_remove

Replace read values with `Vec::swap_remove` instead inserting dummy value.
The reason is that `Vec::remove` is O(n)

* address review grumbles: batch trait bound Default

* don't be clever

* [http client]: faster lookup for batch request.

* fix: distguish request_id and batch_id
