On diskless SN, the nodes file of goconserver is missing when
reinstalling. This patch add a column in nodehm table to help
recover the console information on service node.

Add `-q|--query [noderange]` for makegocons to list the console
status and the host server. If node is not registered in
goconserver, the status will be `unregistered`.
If console releated attribute is not defined for the specified
node but it is included in the noderange, error message for that
node will be printed at first.
Split attribute with comma is not a standard way, this commit
bumped REST version to 1.0 to deal with these attributes in
array type.

- clear logs in the key components during provisioning (not only debug mode, but debug mode will have more logs)
- now only cover rhel7 stateful and stateless
- make more syslogs into cluster.log (tag = xcat or xcat.*)
- the changes will not impact other distro
