Kevin Benton 70907b3e55 Always cleanup stale devices on DHCP setup failure 
If the DHCP port setup process fails in the DHCP agent device
manager, it will throw a conflict exception, which will bubble
all of the way up to the main DHCP agent. The issue is that, during
a 'restart' call, the config files are wiped out while maintaining
the VIF before calling setup. This means that, if setup fails, there
is no reference to the interface name anymore so a subsequent destroy
will not first unplug the VIF before destroying the namespace.
This leaves a bunch of orphaned tap ports behind in the OVS case
that don't have an accessible namespace.

This patch addresses the issue by cleaning up all ports inside of
a namespace on a 'setup' failure before reraising the exception.
This ensures that the namespace is clear if destroy is called in the
future without another successful setup.

Closes-Bug: #1625325
