1. common.Backoff now implements jitter instead of sleeping for a fixed … …

   …amount of time (elastic#10177)
   
   This PR add a new interface called backoff.Backoff, this can be used to
   generalize any backoff interaction. It move the current Backoff strategy
   under an ExpBackoff type.
   
   ExpBackoff is the same as before on every wait we just
   exponentially increase the duration of the wait and sleep for that
   amount.
   
   EqualJitterBackoff uses an exponential increment of the duration but
   will take half of that value as fixed sleep time and the other half
   as a jitter. This will help distribute the new request when a cluster is
   done instead of having all the beats trying to reconnect at once.
   
   The Redis implementations and any clients wrapped with a backoff will
   now use the EqualJitterBackoff, any other code will keep using the same
   exponential strategy.
   
   Fixes: elastic#10172
