ocfs2: add clustername to cluster connection
This is an effort of removing ocfs2_controld.pcmk and getting ocfs2 DLM handling up to the times with respect to DLM (>=4.0.1) and corosync (2.3.x). AFAIK, cman also is being phased out for a unified corosync cluster stack. fs/dlm performs all the functions with respect to fencing and node management and provides the API's to do so for ocfs2. For all future references, DLM stands for fs/dlm code. The advantages are: + No need to run an additional userspace daemon (ocfs2_controld) + No controld device handling and controld protocol + Shifting responsibilities of node management to DLM layer For backward compatibility, we are keeping the controld handling code. Once enough time has passed we can remove a significant portion of the code. This was tested by using the kernel with changes on older unmodified tools. The kernel used ocfs2_controld as expected, and displayed the appropriate warning message. This feature requires modification in the userspace ocfs2-tools. The changes can be found at: https://github.com/goldwynr/ocfs2-tools branch: nocontrold Currently, not many checks are present in the userspace code, but that would change soon. This patch (of 6): Add clustername to cluster connection.
