Improve interceptor registration order by letting users decide it.

[arthurfiorette]

First of all these are in the reverse order (source).

The request cache interceptor should be the first one to execute and the response interceptor should also be the first one to resolve by default. This way, retry/rate limiter interceptors will only handle requests that would actually go through the network.

Ideal registration order would be like this:

1. any request interceptor
2. axios request interceptor as last
---
1. axios response interceptor as first
2. any response interceptor

Our current api suggests the use of setupCache(Axios.create()), which mostly forces the usage of the following order:

1. axios request interceptor as fist   <-
2. any request interceptor             <-
---
1. axios response interceptor as first
2. any response interceptor

which are caused by these lines:

axios-cache-interceptor/src/cache/create.ts

Lines 93 to 94 in b731b2c

	axiosCache.requestInterceptor.apply();
	axiosCache.responseInterceptor.apply();

My current idea is to do these 3 following ways:

// This calls to register the request and response interceptor. no need to setupInterceptor();
// Desired default to avoid breaking changes.
const axios = setupCache(Axios.create(), { attach: true } )//

// only registers the response interceptor.
// Should only be default in the next major version.
// (Or maybe we push a new version now alongside with other PR changes that are open)
// because this is a super easy and fixable breaking change
const axios = setupCache(Axios.create(), { attach: 'headless' })

// this calls to register the request interceptor.
axios.setupInterceptor();

// In case you want full modularity
const axios = setupCache(Axios.create(), { attach: false })

// this calls to register the request and response interceptor.
// maybe a different method/parameter to be possible to register each separatelly?
axios.setupInterceptor();
