Poll Delay should be configurable in config file for resources

[Tony Lin]

For the individual resource convergence check tasks, it would be much easier to tune for scale the frequency of the resource checks if the Poll Delay intervals were configurable. This can go under [clients_cinder] for example:

[clients_cinder]
cinder_poll_delay = 3

and within the relevant check_*_complete code, trigger PollDelay with

raise PollDelay(int(cfg.CONF.clients_cinder.cinder_poll_delay))
