Add jittered delay during replication error handling
For one-to-many replications, when source fails, it can create a stampede
effect. A jittered delay is used to avoid that. Delay is random, in a range
proportional to current number of replications, with a maximum of 1 minute.
Seed random number generator within each replication process with a
non-deterministic value, otherwise the same sequence of delays is generated
for all replications.

> Source failure in one source to many target replications causes a stampede

> For multiple replications from a single source to multiple targets. If source
> fails, all replications post an error state back their replication document
> and attempt to restart. This creates a stampede effect and causes sharp load
> spikes on the replication cluster.
