repmgr: set "synchronous_commit" to "local" by default

Browse Source 
Rather than set this for individual connections, we'll change the setting
each time a connection is made (except replication connections), which will
obviate the need to take this into consideration when making connections
in the application code.

Resolves GitHub #276.
