746e7dc42e The attached patch is a try to make clvmd work correctly on openais stack. 
It does 2 things.

1. The cpg_deliver_callback make a compare between target_nodeid and our_nodeid.
It turns out openais set target_nodeid to 0 sometimes. for broadcasting ? I change the behavior so that lvm will process_remote also on target_nodeid == 0

2. The joined_list passed to cpg_confchg_callback doesn't include the already exist nodes in the group, which leads to an incomplete node_hash. I simply add all other nodes in member_list to node_hash also.

Thanks to Xinwei Hu for this patch.

e8d3d71e23 Add config file overrides to clvmd when it reads the LVs list so that 
config items 'command_names' and 'prefix' don't prevent it working.

ec074fcf64 If lvm.conf was touched, clvmd attempted to update the toolcontext 
but only did half of the job. It now shares the do_refresh_cache()
function that vgscan invokes.
