Currently there is no support to get console in dev and
test environments, this patch implements a console driver
ShellinaboxConsole to add ability of console access for
SSH driver using 'virsh console'.
For non-virsh ssh drivers, a 'GET /v1/drivers/properties'
request will return False for the console interface (as
opposed to None) with a 'not supported ...' reason.
