rsync: add key refresh retry (bug 649276)

Since key refresh is prone to failure, retry using exponential
backoff with random jitter. This adds the following sync-openpgp-*
configuration settings:

sync-openpgp-key-refresh-retry-count = 40

  Maximum number of times to retry key refresh if it fails.  Between
  each  key  refresh attempt, there is an exponential delay with a
  constant multiplier and a uniform random multiplier between 0 and 1.

sync-openpgp-key-refresh-retry-delay-exp-base = 2

  The base of the exponential expression. The exponent is the number
  of previous refresh attempts.

sync-openpgp-key-refresh-retry-delay-max = 60

  Maximum  delay between each retry attempt, in units of seconds. This
  places a limit on the length of the exponential delay.

sync-openpgp-key-refresh-retry-delay-mult = 4

  Multiplier for the exponential delay.

sync-openpgp-key-refresh-retry-overall-timeout = 1200

  Combined time limit for all refresh attempts, in units of seconds.
