/**
* Create a cache session
*
* A cache session represents a client's access into the cache. The cache
* session is not "owned" by the cache service. Hence, it is possible to
* create duplicate cache sessions. Entries created by a cache session
* are invisible to other cache sessions, unless the cache sessions are
* equivalent.
*
* @param clientID - Specifies the name of the client using the cache.
* @param storagePolicy - Limits the storage policy for all entries
* accessed via the returned session. As a result, devices excluded
* by the storage policy will not be searched when opening entries
* from the returned session.
* @param streamBased - Indicates whether or not the data being cached
* can be represented as a stream. The storagePolicy must be
* consistent with the value of this field. For example, a non-stream-
* based cache entry can only have a storage policy of STORE_IN_MEMORY.
* @return new cache session.
