Need to add id to fuel `graph list` command

[Alexandr Kostrikov]

There are a lot of options to view graph
usage: fuel2 graph list [-h] [-f {csv,html,json,json,table,value,yaml,yaml}]
                        [-c COLUMN] [--max-width <integer>] [--noindent]
                        [--quote {all,minimal,none,nonnumeric}]
                        [-s SORT_COLUMN [SORT_COLUMN ...]] -e ENV

For instance there is possible command:
>[root@nailgun ~]# fuel2 graph list -e 1 -c tasks -f csv
>"tasks"
>""
>"custom_task_on_ceph-osd, custom_task_on_cinder, custom_task_on_compute, custom_task_on_controller"

But it would be really useful to skip table header(if I know that items are on one column -c tasks)
And non needed for me first line on default graph.
>[root@nailgun ~]# fuel2 graph list -e 1 -c tasks -f csv -id 6
>"custom_task_on_ceph-osd, custom_task_on_cinder, custom_task_on_compute, custom_task_on_controller"
