Refresh access token if its about to expire

For every request access token ,refresh token are sent as cookies to the server
- send an expiry time cookie which has unix time stamp of the expiry date, generate this when access token is generated
- for every future request in the base handler, check the current time stamp and the expiry time stamp
- if it is about to expire in about lets say 5 min, send the request to refresh endpoint
- get the refresh token from the cookie and talk to spotify via their api and save the access, refresh token and expiry unix time stamp
- finally send the request to base url
