Changes in repmgr are:

- Add checks to test if the directories are useful for us (basically
  the checks follow the same approach as initdb does)
- Add connection parameters
- Better use of rsync
- Some more clean up of code

Changes in repmgrd are:
- Add a parameter to allow the user specify an repmgr.conf
- Change the name of the repl_status table for repl_monitor
- Create a repl_status view that also shows lag in time
- Some more clean up of code
