Eric Fried 11a5fcbb6a Allow resource_provider_association_refresh=0
With this change, [compute]resource_provider_association_refresh is
allowed to be zero, which will disable refreshing resource provider
traits and aggregates.

Inventories are still refreshed in a different code path.

A subsequent patch will be submitted to allow manual refresh by sending
SIGHUP to the compute process.

The configuration option
``[compute]resource_provider_association_refresh`` can now
be set to zero to disable refresh entirely. This follows on from `bug
1767309`_ allowing more aggressive reduction in the amount of traffic to
the placement service.
