extra_dhcp_opt add checks for empty strings

When passing extra-dhcp-opt into the port-create where an empty string
is provided as opt_value='   ', the create and update routine will load the
empty string into the DB. The result when written to the opts file is:
"tag:ece4c8aa-15c9-4f6b-8c42-7d4e285734bf,option:server-ip-address", which
when read by dnsmasq has been tested to cause dnsmasq to segment fault.

Add support for NSX/NVP Metadata services

This is a feature patch (2 of 3) that adds support for
Metadata services provided by the NSX (aka NVP) platform.

It also implements the handling of port events so that
dhcp and metadata configuration in NSX/NVP is updated
if port attributes such as fixed_ips and device_id are
updated.

Change default eswitchd port to avoid conflict

Previous default for eswitch/daemon_endpoint would set a TCP port (5001)
which is in the range of the well known ports.
Change to unreserved port (60001) will avoid that conflict.
