29 * This class maintains a cache of information by provider, where a provider is identified by both a type and an
30 * identity URL used to connect to that provider.

33 * another. Therefore, the provider cache maintains a cache of tenants and the service catalogs for each, as well as the
34 * credentials used to access the tenants, and a pool of Context objects for each tenant. The context pool allows use of
35 * the CDP abstraction layer to access the services of the provider within the specific tenant.
