cli: add room

add functionality to add and remove a room

to add a new room use the command: ogcli add room --name <name>
--netmask <netmask> --center <center> --gateway <gateway> [--location
<location>] [--ntp <ntp>] [--dns <dns>] [--group <group>]

for instance, to create a room with name 'dummyroom', netmask
'255.255.255.0' and gateway 10.141.10.1 that is inside the center with
id 1, use:

$ ogcli add room --name dummyroom --netmask 255.255.255.0 --gateway
10.141.10.1 --center 1

Optionally, it is possible to provide additional information such as
location (--location <location>), ntp server (--ntp <ntp>), dns server
(--dns <dns>), and a group to contain the room (--group <group>).

to delete a room use: ogcli delete room --id <id>

for instance, to delete room with id 4 use:

$ ogcli delete room --id 4
