Ensure jsonrpc threading settings are sane (#11267) 

* Ensure jsonrpc threading settings are sane

Starting with `jsonrpc` v14, the "server threads" setting is more important than before and the current default of 1 means the https server is effectively single-threaded. This PR proposes a new default of 4 (and ensures that crazy settings like e.g. `0` are bumped to at least `1`).

Also included: some docs, tests and cosmetics.

* Update parity/rpc.rs

* Update parity/rpc.rs

Co-Authored-By: Tomasz Drwięga <tomusdrw@users.noreply.github.com>

* Remove (i.e. deprecate) `--jsonrpc-threads` command line option

* Call numbers NUM

* Don't show a default for --jsonrpc-threads (deprecated)

* Show deprecation warning when using `--jsonrpc-threads` or `processing_threads`

* Update parity/deprecated.rs

Co-Authored-By: Niklas Adolfsson <niklasadolfsson1@gmail.com>

* Fix test

* Fix tests for real
