Full flavor CRUD

Flavor CRUD v2

To use the low level api for the resource:

    from openstack.compute.v2 import flavor
    resp = flavor.Flavor.get_data_by_id(sess, '102')

The resp will be a dictionary.

Make logging more efficient in transport

Currently, transport does all the string format work on the request
and then it tries to log it without checking first if it is even
going to print.  This is low enough level code that it should be
more efficient.

Separate head restrictions from get

We need to be able to allow head requests while disallowing get
requests. In swift, we want to be able to call head on the account
for metadata, but will be listing containers - both of which are calls
on the root URL - from a different class
