High: nfsserver: Improve support for v3 file lock recovery

The nfs-lock daemon may look in /var/lib/nfs/sm or
/var/lib/nfs/statd/sm depending on the version. This patch detects
if the statd folder should be used for lock failover.

Low: doc: fix spelling and improve style in meta-data (thanks to the SUSE documentation team)
Medium: ethmonitor: correctly detect when the network is unplugged.

The ethmonitor does not return the correct status
1). when the wire is unplugged from network interface,
    for example, the output for eth0 is:
    # ip -o link show up dev eth0
    # eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state
DOWN qlen 1000
2). when lower layer is down for a VLAN, for example, the output:
    # ip -o link show up dev vlan2
    # vlan2@bond2: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc
noqueue state LOWERLAYERDOWN

Solution:
    both of the above status can be detected by 'grep NO-CARRIER'

Linbit packages their own drbd ocf agent outside of the

provider is deprecated in favor of the Linbit provider one.
