EXPERIMENTAL: synchronise try_primary_reconnect()'s reconnection loop

Browse Source 
Per proposal in GitHub #662, this patch attempts to synchronise each
repmgrd's primary reconnection attempts to prevent potential race
conditions. This relies on each node's clock being correcly
synchronised.

Currently this change is experimental and is not enabled by default.
It can be enabled by setting the repmgr.conf parameter
"reconnect_loop_sync".
