[rackspace|autoscale] starting on rackspace auto scale implementation
Adding models, collections and making a start on request classes
Merge branch 'auto_scale'
Initial commit for Rackspace's new Autoscale features. Most functionality is incorporated, including:
- Scaling groups
- Configuration (group configuration and launch configuration)
- Scaling policies
- Webhooks

Work remaining includes:
- Mock request classes
- Unit test coverage
Removing two superfluous files
Shindo tests are completed; finished adding Mock data
Merge branch 'master' of github.com:jamiehannaford/fog
Adding a few more ensure blocks for resource deletion
Modifying array for 1.8.7 Gemfile to pass
Removing trailing slashes from method calls for 1.8.7
fix missing record data in dynect dns

currently, when fog requests all records:
* make a NodeList request
returns a list of nodes (domains)
* for each domain, make a secondary AnyRecord request for each domain
returns a list of records (without data)

The resulting Record objects do not contain the data of where the record points (address or cname). 'rdata' is nil

I've changed the process to be:
* make an AllRecord request
returns a list of records (without data)
* make a secondary request to *Record (using the type returned from the AllRecord request)
this returns a *complete* record object (including data)

The number of requests to Dynect API is the same, but the resulting objects contain all of the information.

TODO:
* Please help me integrate with fog testing
* I had to remove (comment) the API Version header, not sure what the correct value for this is
** Dynect documentation is a bit difficult to work through
remove commented code and update API version
add get_node_list request again, add test for get_all_records request
speed things up for get calls. add find_by_name filter. still needs some refactoring
remove find_by_name for now
options not used. return nil unless we find a matching url in response
Fixing minor issues with doc annotations, removing unused file, adding Shindo tests
Adding the red herrings
Local storage's File quacks like other Directories

Even though it doesn't accept any options, it'd be nice if it accepted
them anyway in the name of duck typing and allowing backends to be more
swappable.
