Description
In minigraph.py:

            if vintf.find(str(QName(ns, "DhcpRelays"))) is not None:
                vintfdhcpservers = vintf.find(str(QName(ns, "DhcpRelays"))).text
                vdhcpserver_list = vintfdhcpservers.split(';')
                vlan_attributes['dhcp_servers'] = vdhcpserver_list

This will crash upon case of <DhcpRelays></DhcpRelays>, i.e. vintf.find(str(QName(ns, "DhcpRelays"))) is not None but vintf.find(str(QName(ns, "DhcpRelays"))).text is None.

Steps to reproduce the issue:
Create a minigraph with <DhcpRelays></DhcpRelays> in <VlanInterface> section, then sonic-cfggen -m.

I feel like the scope of this issue is larger than just the <DhcpRelays></DhcpRelays> tag, and could pose an issue with any tag that contains no data. I think we should either:

a.) Explicitly not allow empty tags (therefore undefined behavior is acceptable)

OR

b.) Add support throughout minigraph.py to gracefully handle empty tags.

option b is preferred.
