Implement a Heat-native resource group

This resource allows for creating groups of identically
configured resources via nested stacks. It provides
aggregated as well as indexed access to the nested
resource attributes.

Remove Component class

Discussion has moved on from implementing components as
top-level template elements, so this can be deleted now.

Make heat depend on python-heatclient

This will be required soon for one or more of the
following reasons:
* Multi-region invoking stacks on other heat endpoints
* A variant of nested stack which goes through API instead of
  internally
* Orchestrating new heat-based resources (autoscaling, software config)
* Possibly sharing some template parsing and validation between
  client and server by moving this code to client

Add a missing mock to rackspace cloud server test

A few tests were missing a mock call, which led the tests into an

Add exact filter support to SQL API list stacks

Uses a dict of KEY:VALUE to compare values of VALUE against database
attribute KEY and return matching stacks.  If VALUE is a list, tuple,
set, or frozenset, this will evaluate to an IN clause instead.

FaultWrapper error mapping supports parent classes

Now the FaultWrapper middleware maps exceptions to webob ones using
a recursive method: if the exception itself is not in the error_map
dictionary, the method searches the first parent exception that has a
match in the same dictionary.
Without this change "any exception that subclasses an exception mapped
in FaultWrapper.error_map will raise an http 500 error instead of the
mapped http error. FaultWrapper should also map against all parent
types of an exception."
Two unit test were added: one to reproduce the bug and another to test
the fix when remote exceptions are handled.

Add filter support to stack API

Accepts multiple request params ATTR=VALUE to filter the listed
stacks.  Stacks will be matched against all whitelisted filters
passed in the request.  Whitelisted filters for stacks are NAME
and STATUS.

If the same ATTR is passed multiple times, stacks matching ANY of the
values will be returned.

Define deletion policy constants

Defining resource deletion policies 'Delete', 'Retain',
'Snapshot' as constants because these values are used more
than once and also in multiple modules.

Adds ability to configure various clients used by the Heat

This commit adds config sections [clients_nova], [clients_swift],
[clients_neutron], [clients_cinder], [clients_ceilometer] and
[clients_keystone]. These sections contain additional configuration
options for corresponding OpenStack clients.
Currently those are only SSL-related setting ca_file, cert_file,
key_file and insecure. Note, than not every client library is
currently capable of utilizing all of the SSL settings.

There is also a plain [clients] section that holds shared client
options. Each option searched first at specific group (clients_xxx)
and if it not found there then the value from [clients] group
are taken (or default values if there is no such setting in this
group). This allows defining shared configuration that would be
used by most (or all) clients without repeating the same settings
for each and every client separately
