Multiple Bearer Token Fetching

[dan-mcm]

Currently a new bearer token is requested everytime a call to twitch is made, segment this logic out so its only fetched once every hour or so and written to a variable or some similar config solution.

sub-issue -> duplication call of getBearerToken -> should be able to implicitly pass the token downwards instead of asking additional details

As using Promise.all this can definitely be optimzed now.
