Refactor `<AccessType>` component

[asimqt]

There are some architectural issues with our current <AccessType> component which I'm noting here: These issues made working with the component hard:

1. on componentDidMount we're calling initAccessType which makes the subsequent calls like this.getSubscription() and this.getPaymentOptions() always happening if somehow the component is re-mounted. This is not needed as we should let the users of the component decide when to call initAccessType as we're exposing it through renderProp anyway. The component calling itself counter the full renderProp idea.
   Note: when removing make sure the users of <AccessType> are calling initAccessType explicitly when needed.
2. API calls like this.getPaymentOptions() should be cached in memory.
3. There should be more exposed helper functions like setUser and getJWTToken and try to memoize the results.
