Set the tcmur_cmd_time_out=43s as default, which is larger than
each IO's timeout value(default is 30s) in the client/initiator side,
and at the same time it will be larger than 42s, the Gluster ping
timeout.

This will still need to depend the taregetcli's saveconfig support,
the rtslib PR is open-iscsi/rtslib-fb#150.

In case all the ha nodes have supported the rtslib-fb#150:
1) if local node support the block-size, but if there is any of
the remote nodes is not, it will fail with the cap not match error.
2) if local node does not support the block-size, no matter whether
the remote nodes support it or not, it will always ignore the

Simple 2 node setup demo:
* on server node:
- runs glusterd (glusterfs-server) and gluster-blockd daemon
- where we create a block hosting volume and then create a block volume on it
* on client node:
- runs iscsid daemon
- where we login to previously created block volume and perform some IO

It looks like 24006 port is already registered by some other service,
and from [1] it looks like 24007 - 24241 are unassigned.
Currently,
24007 -> glusterd (tcp)
24008 -> glusterd (rdma)
24009 -> glustereventsd
so for gluster-blockd communications lets choose port 24010
