Add missing quota flags in the config file sample

l3 extensions don't set quota flags in the config sample file
etc/neutron.conf.
Quota is unlimited if its value is minus and not only if it's -1.

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".

Send DHCP notifications regardless of agent status

The Neutron service, when under load, may not be able to process
agent heartbeats in a timely fashion.  This can result in
agents being erroneously considered inactive.  Previously, DHCP
notifications for which active agents could not be found were
silently dropped.  This change ensures that notifications for
a given network are sent to agents even if those agents do not
appear to be active.

Additionally, if no enabled dhcp agents can be found for a given
network, an error will be logged.  Raising an exception might be
preferable, but has such a large testing impact that it will be
submitted as a separate patch if deemed necessary.

Start of new developer documentation

There is currently no useful developer-focused documentation in-tree
for Neutron. There are a smattering of useful documents on the
OpenStack wiki, however, there isn't a good organization to this
information, nor is there a condensed developer focus to a lot of it.
Some of the wiki pages are more proposals for features or bug fixes,
and there is a need for architecture, design, and code walk-through
documentation for Neutron to help with new (and existing) contribution.

This patch begins the process of adding developer documentation to Neutron.
It updates the main developer reference index.rst to pull in-line with what
Nova is doing, leaving some todo references for future patches. It also
adds a development.environment tutorial that is up-to-date with current
Neutron development, using tox/testr processes for running unit tests and
including a number of references to external wiki pages that have
instructions for using DevStack for OpenStack contribution/testing.

The next series of patches will add automodule documentation to the
developer reference for some of the major modules in Neutron.

nicira: fix db integrity error during port deletion

Due to the fact that plugin port operations are not
transactional (as they involve non synchronized DB
and Controller operations), concurrent (interleaved)
port requests may accidentally cause the insertion
of the mapping entry (neutron-port-id, nvp-port-id)
more than once. In case this occurs, it's safe to
expect the failure and continue the normal process
of the operation being requested.
