feature request: onFetchUser hook for local strategy

[reslear]

like $auth.onRedirect
and extend axios interceptor between hook resetInterceptor

motivation:

• do not use autoFetch: false
• do no write more code for custom fetching nuxt-auth module not setting loggedIn and user value #209 (comment)
• passing extra query params like feat(oauth2): support passing extra query params #358

draft:

// plugins/auth.ts
$auth.onUserFetch((config: AxiosRequestConfig) => {
  config.params['lang'] = app.i18n.locale;
  app.$toast.show('getting user...');
  return config;
});

or refactor Interceptor and resetInterceptor for available in$axios.onRequest
thx

temporary solutions for use params:

// plugins/auth.ts
$auth.strategies.local.options.endpoints.user.url = `${BASE_URL}/api/user?lang=${app.i18n.locale}`;

and combine hook i18n.beforeLanguageSwitch with this.$auth.setUser(user)

or use vuex for store user data and fetch in nuxtServerInit
