adding a new device
example post /device/new
macaddress,group
removing an existing device

listing vlans
GET /vlan/
SELECT * FROM `radgroupreply`
this will return 3 duplicate "groupnames" with different attribute and vlaue
only need to return group name and value for Tunnel-Private-Group-Id

adding new vlan
need to add 3 items with different attribute and value, 
for example to add staff vlan with vlan ID 55
api call should be like POST vlan/add and json data vlanid:55, alias staff

'INSERT INTO `radgroupreply` (`groupname`, `attribute`, `op`, `value`)
VALUES ('staff', 'Tunnel-Type', '=', 'VLAN');

INSERT INTO `radgroupreply` (`groupname`, `attribute`, `op`, `value`)
VALUES ('staff', 'Tunnel-Medium-Type', '=', 'IEEE-802');

INSERT INTO `radgroupreply` (`groupname`, `attribute`, `op`, `value`)
VALUES ('staff', 'Tunnel-Private-Group-Id', '=', '55');
'
deleting existing vlan
you get api call to delete vlan 
DELETE vlan/55
and the sqlcommands should you looking for Tunnel-Private-Group-Id=55 and then deleting all the maching group names

edit existing vlan (alias)
post request, and allow to edit alias 

disallow to add duplicate vlans or alias

listing existing devices
get /device/
SELECT * FROM `radusergroup`
and then 
SELECT * FROM `customers`
return mac address, groupname and status

adding new device
this input feils are 
'
POST /device/add with mac address and group and it involves few Commands
`
SELECT * FROM `radgroupreply` 
# and see if the group in the device add command exists
# respond 4xx (whatever needed with reason group not found)
# else continue

INSERT INTO `radcheck` (`username`, `attribute`, `op`, `value`)
VALUES ('14-99-3E-74-CB-7F', 'Cleartext-Password', ':=', '14-99-3E-74-CB-7F');

INSERT INTO `radusergroup` (`username`, `groupname`, `priority`)
VALUES ('14-99-3E-74-CB-7F', 'staff', '1');

INSERT INTO `customers` (`username`, `mac_address`, `status`, `created_at`)
VALUES ('14-99-3E-74-CB-7F', '14-99-3E-74-CB-7F', 'paid', now());
`

deleting existing deivce
edit existing device (input macaddress, edit groupname, edit status. do allow to edit just 1 feild) 
use sesnible commands based on add devices

i would also like a device alias, added to customers table like 
"Customer name, device name, phone number"
these are to be ignored by radius server, but helpful for human review 
and add input fields during adding device and also listing devices
