About user specified vlan

[YufengXin]

From atlanticwave-sdx/sdx-controller#232

@italovalcy As I can see, the vlan_range is [1-100] and you were asking vlan 107 in your request. 107 is outside of the OXP available vlan range, in which case, the current logic would just pick an available one to assign to your request.

A while ago, we agreed to retire the 'sdx-continuous-development' repo. Now you made it work, we could look at it again. (1) could you please make thees instruction into the readme in that repo?
Hi @YufengXin actually, if you see the requests I created two tests: 1) first using VLAN 107, which is outside of the range allowed from the OXP; 2) I created a second test using VLAN 49, inside the VLAN range and still got assigned VLAN 100....

For situation 1, the SDX-Controller has to reply saying that the requested VLAN is not allowed, instead of creating a VLAN of the choice of the SDX-COntroller.

For situation 2, the SDX-Controller just ignored the request from the user and assigned a VLAN of its choice again..

(2) For the timebeing, we only need to run unittest for debugging, would you be able to save these three OXP topology.json and check them in to the tests/data in 'datamodel' repo? Thanks.
In this case you just need to run the same steps as I did before and you should be able to get the JSONs! ;)
