Partition swift pollster resources by tenant

Since the latest discovery change, Swift pollsters on different
agents only decide which who should poll. Most of the time there's
only one endpoint, so only one agent gets to do any work.

This patch fixes this by introducing a new TenantDiscovery, which
enables Swift (and other in the future) pollsters to partition the
set of keystone tenants among them and then each poll the samples
for their assigned subset of tenants.
