If cons script is waiting, goconserver could not aware of
the status of the console connection. This patch check
the environment when running the script, if it is gocons
and retrying is needed, exit immediately.
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.
