Update infrastructure to more closely match other OpenStack projects

This patch imports nova's HACKING.rst guidelines altered for Heat.
This patch imports nova's run_pep8.sh with some minor alterations.
This patch imports nova's hacking.py extensions to pep8.

This patch places the run_pep8 logic in a separate file rather than
having it spread between tox.ini and run_tests.sh.  The HACKING.rst
requirements as well as general pep8 requirements are then enforced
with run_pep8.sh.

Avoid running once the N802 rule until dependency changelogs are
less then 50 characters.

Glance Style Commandments
Heat Style Commandments
=======================
- Step 1: Read http://www.python.org/dev/peps/pep-0008/
@ -9,18 +9,62 @@ Glance Style Commandments
General
-------
- Put two newlines between top-level code (funcs, classes, etc)
- Use only UNIX style newlines ("\n"), not Windows style ("\r\n")
- Put one newline between methods in classes and anywhere else
- Long lines should be wrapped in parentheses
in preference to using a backslash for line continuation.
- Do not write "except:", use "except Exception:" at the very least
- Include your name with TODOs as in "#TODO(termie)"
- Do not name anything the same name as a built-in or reserved word
- Do declare variable names that conflict with the debugger, such as the letter 'c'
- Do not shadow a built-in or reserved word. Example::
def list():
return [1, 2, 3]
mylist = list() # BAD, shadows `list` built-in
class Foo(object):
def list(self):
return [1, 2, 3]
mylist = Foo().list() # OKAY, does not shadow built-in
- Use the "is not" operator when testing for unequal identities. Example::
if not X is Y: # BAD, intended behavior is ambiguous
pass
if X is not Y: # OKAY, intuitive
pass
- Use the "not in" operator for evaluating membership in a collection. Example::
if not X in Y: # BAD, intended behavior is ambiguous
pass
if X not in Y: # OKAY, intuitive
pass
if not (X in Y or X in Z): # OKAY, still better than all those 'not's
pass
Imports
-------
- Do not import objects, only modules (*)
- Do not import more than one module per line (*)
- Do not use wildcard ``*`` import (*)
- Do not make relative imports
- Do not make new heat.db imports in heat/virt/*
- Order your imports by the full module path
- Organize your imports according to the following template
(*) exceptions are:
- imports from ``migrate`` package
- imports from ``sqlalchemy`` package
- imports from ``heat.db.sqlalchemy.session`` module
- imports from ``heat.db.sqlalchemy.migration.versioning_api`` package

Docstrings
----------
Example::
Docstrings are required for all functions and methods.
Docstrings should ONLY use triple-double-quotes (``"""``)
Single-line docstrings should NEVER have extraneous whitespace
between enclosing triple-double-quotes.
**INCORRECT** ::
"""A one line docstring looks like this and ends in a period."""
""" There is some whitespace between the enclosing quotes :( """
**CORRECT** ::
"""A multi line docstring has a one-line summary, less than 80 characters.
"""There is no whitespace between the enclosing quotes :)"""
Then a new paragraph after a newline that explains in more detail any
general information about the function, class or method. Example usages
are also great to have here if it is a complex class for function.
Docstrings that span more than one line should look like this:
Example::
"""
Start the docstring on the line following the opening triple-double-quote
When writing the docstring for a class, an extra line should be placed
after the closing quotations. For more in-depth explanations for these
decisions see http://www.python.org/dev/peps/pep-0257/
If you are going to describe parameters and return values, use Sphinx, the
appropriate syntax is as follows.

submitted bug fix does have a unit test, be sure to add a new one that fails
without the patch and passes with the patch.
For more information on creating unit tests and utilizing the testing
infrastructure in OpenStack Heat, please read heat/testing/README.rst.
Running Tests
-------------
The testing system is based on a combination of tox and testr. The canonical
approach to running tests is to simply run the command `tox`. This will
create virtual environments, populate them with depenedencies and run all of
the tests that OpenStack CI systems run. Behind the scenes, tox is running
`testr run --parallel`, but is set up such that you can supply any additional
testr arguments that are needed to tox. For example, you can run:
`tox -- --analyze-isolation` to cause tox to tell testr to add
--analyze-isolation to its argument list.
It is also possible to run the tests inside of a virtual environment
you have created, or it is possible that you have all of the dependencies
installed locally already. In this case, you can interact with the testr
command directly. Running `testr run` will run the entire test suite. `testr
run --parallel` will run it in parallel (this is the default incantation tox
uses.) More information about testr can be found at:

Commit Messages
---------------
Using a common format for commit messages will help keep our git history
readable. Follow these guidelines:
First, provide a brief summary (it is recommended to keep the commit title
under 50 chars).
The first line of the commit message should provide an accurate
description of the change, not just a reference to a bug or
blueprint. It must be followed by a single blank line.
If the change relates to a specific driver (libvirt, xenapi, qpid, etc...),
begin the first line of the commit message with the driver name, lowercased,
followed by a colon.
Following your brief summary, provide a more detailed description of
the patch, manually wrapping the text at 72 characters. This
description should provide enough detail that one does not have to
refer to external resources to determine its high-level functionality.
Once you use 'git review', two lines will be appended to the commit
message: a blank line followed by a 'Change-Id'. This is important
to correlate this commit with a specific review in Gerrit, and it
should not be modified.
For further information on constructing high quality commit messages,
and how to split up commits into a series of changes, consult the
project wiki:
