marsadm: change defaults for *{,-local,-global} 

By default, {dis}connect and {pause,resume}-{replay,sync} should
only switch the _local_ buttons. Otherwise, unexpected side-effects
could result at bigger clusters (#nodes >> 2) from a human point of view.

The new behaviour is different from DRBD, but DRBD was (until recently)
only working on _pairs_, so global spreadout was impossible.

Global switching may be requested at any time by appending suffix
"-global", which is just no longer the default in MARS.

If anyone has objections, it is straightforward to change the
defaults again.
