[PATCH v2 2/6] kdump-lib: add common variables and function for fence kdump

[WANG Chao]

Add following common variables and function:

$FENCE_KDUMP_CONIFG: configuration file /etc/sysconfig/fence_kdump
$FENCE_KDUMP_NODES: configuration file /etc/fence_kdump_nodes
$FENCE_KDUMP_SEND: executable /usr/libexec/fence_kdump_send
is_fence_kdump(): used to determine if the system is in a cluster and
configured with fence_kdump.
