[Issue] Make Apollo links customizable

[m2-assistant[bot]]

This issue is automatically created based on existing pull request: magento/pwa-studio#3842: Make Apollo links customizable

---

Description

Allow Apollo links to be customized by a configureLinks prop to Adapter / useAdapter. Also, while we're at it, extract the links into their own modules.

This can either follow #3757 or we can combine them here.

New component/talon signature

function configureLinks(linksMap) {
  // receive a map
  // return either a map or array, with modifications
  return Array.from(linksMap.values())
}

const tree = (
  <Adapter
    apiBase="https://example.com/graphql"
    configureLinks={configureLinks}
    store={store}
    styles={styles}
  />
)

New package structure

peregrine
|- lib
  |- Apollo
    |- links
      |- authLink.js
      |- errorLink.js
      |- gqlCacheLink.js
      |- index.js
      |- mutationQueueLink.js
      |- retryLink.js
      |- storeLink.js
