James E. Blair 8dc6c870f2 Add ProviderManager 
This is used to serialize all access to an individual provider
(nova client).  One ProviderManager is created for every provider
defined in the configuration.  Any actions that require interaction
with nova submit a task to the manager which processes them serially
with an appropriate delay to ensure that rate limits are not hit.

This solves not only rate-limit problems, but also ends multi-threaded
access to a single novaclient Client object.

Developer setup:

mysql -u root

mysql> create database nodepool;
mysql> GRANT ALL ON nodepool.* TO 'nodepool'@'localhost';
mysql> flush privileges;

nodepool -d -c tools/fake.yaml

After each run (the fake nova provider is only in-memory):

mysql> delete from snapshot_image; delete from node;
