#2995 rded: allow active SC to be preferred during a split network event

[Gary Lee]

[#2795] added ability to select an SC from the largest partition during a split network event. This is not always desirable; it may be preferable for an application to select the current active SC, even if it resides in a smaller network parition. We should make this behaviour configurable, by adding a parameter to fmd.conf

export FMS_TAKEOVER_PRIORITISE_PARTITION_SIZE=0/1

[Gary Lee]

will be done as part of [#2996]
