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.
