Add ability to ignore provider quota for a pool

In some circumstances it is useful to tell the launcher to
ignore the provide quota and just trust the max-* settings
for that pool instead.

This particular need arises when using Rackspace public cloud
for both instances and OnMetal nodes. In this situation the
quota for instances and for OnMetal nodes is different, but
nodepool only queries the quota for instances. When trying to
build OnMetal nodes, the quota check fails - but should not.

In this circumstance, instead of making shade/nodepool
complicated by figuring out how to calculate disparate quota
types, it makes sense to rather just allow nodepool to ignore
the quota for a pool to try executing the build instead.

While this is our use-case, it may also be useful to others
for other reasons.

A new boolean pool variable ``ignore-provider-quota`` has been added to
allow the provider quota to be ignored for a pool. Instead, nodepool only
checks against the configured max values for the pool and the current usage
based on stored data. This may be useful in circumstances where the
provider is incorrectly calculating quota.
