Add post-mortem debug option for tests

Post-mortem debugging, the ability to drop into a debugger with the
execution state that triggered the exception, is very useful in
diagnosing failure conditions.  Our previous test runner, nose,
provided the ability to enable post-mortem debugging on test
failures (via --pdb-failure) and errors (via --pdb).  testr
lacks these options at present, so this change adds support
for enabling post-mortem debugging via an environment variable.
All test-triggered exceptions will result in a post-mortem debugger
being invoked if OS_POST_MORTEM_DEBUG is set to "1" or "True".

Remove start index 0 in range()

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.

Midonet plugin: Fix source NAT

Source NAT rule was being applied on the incorrect port.
It was being applied to the Neutron gateway port, not to
the MidoNet tenant / provider router link port.

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.
