Parameters

[in]	st	A connection to the fencer API
[in]	target	The node that should be fenced
[in]	action	The fencing action (on, off, reboot) to perform
[in]	name	Who requested the fence action?
[in]	timeout	How long to wait for the operation to complete (in ms)
[in]	tolerance	If a successful action for `target` happened within this many milliseconds, return success without performing the action again
[in]	delay	Apply this delay (in milliseconds) before initiating the fencing action (a value of -1 applies no delay and also disables any fencing delay from pcmk_delay_base and pcmk_delay_max)
[out]	reason	If not NULL, where to put descriptive failure reason

Returns: Standard Pacemaker return code

Note: If reason is not NULL, the caller is responsible for freeing its returned value.

Todo:: delay is eventually used with g_timeout_add() and should be guint
