refactor(stack/proxy): make rpc-manager stack component
This commit refactors the `rpc-manager` to be a stack component and therefore
making it available to a variaty of plugins that might need access to its APIs
so they can register new RPC interceptors.
RpcModifiers have been renamed to `rpc-interceptors` and extracted from the `rpc-manager`
source into their own plugin. The reason for the renaming was that modifiers aren't always
modifying RPC APIs, but potentially introduce brand new ones.
There are a bunch of new APIs that can be used to register new RPC APIs:
```
events.request('rpc:request:interceptor:register', 'method_name', requestInterceptorFn);
events.request('rpc:response:interceptor:register', 'method_name', responseInterceptorFn);
function requestInterceptorFn(params: ProxyRequestParams<T>) {
// mutate `params` here
return params;
}
function responseInterceptorFn(params: ProxyResponseParams<T, S>) {
// mutate `params` here
return params;
}
```
A few things to note here:
- `method_name` is either `string`, `string[]`, or `Regex`. This make registering custom RPC
APIs extremely flexible.
- A `requestInterceptorFn()` gets access to `ProxyRequestParams<T>` where `T` is the type of the
params being send to the RPC API.
- A `responseInterceptorFn()` gets access to `ProxyResponseParams<T, S>` where `T` is the type of the
original request parameters and `S` the type of the response coming from the RPC API.
These APIs are used by all `rpc-interceptors` and can be used the same way by any oother plugin
that aims to create new or intercept existing APIs.
