Network gateway vlan connection fails because of int conversion

[Salvatore Orlando]

So far there has been an implicit assumption that segmentation_id would be an integer.
In fact, it is a string value, which was been passed down to NSX.

This means that passing a string value, like "xyz", rather than a validation error would have triggered a backend error.
Moreover, the check for validity of the VLAN tag is now in the form min < tag < max, and this does not work unless tag is converted to integer.

    NSX-mh: fix default l2 gw connections

    This patch fixes connections to the default layer-2 gateway
    ensuring that:
    1) no "None" value is sent for tags to nsxlib. In particular this
       patch ensures that the tenant_id is populated when the request
       is sent with admin credentials.
    2) the segmentation_id attribute is converted to integer before
       validating whether it's a valid VLAN tag.
