Config file values

List of config file options and it's changeability during runtime

Option is in the one of 4 categories:

1. Options which are not changeable during runtime and needs to be in sync with other nodes. It's required to copy corosync.conf and do restart of all nodes.
2. Options which are not changeable during runtime and don't need to be in sync with other nodes. Changing corosync.conf and restarting of the corosync daemon on affected node is enough.
3. Options which are changeable during runtime and needs to be in sync with other nodes. It's required to copy corosync.conf and call corosync-cfgtool -R.
4. Options which are changeable during runtime and don't need to be in sync with other nodes. It's possible to ether use corosync-cmapctl for changing just given key or edit corosync.conf and use corosync-cfgtool -R

Format: key name - changeable during runtime - needs to be in sync with other nodes - Note
