Bug: 190489030
Put a binder cache in front of IDevicePolicyManager APIs. The
following APIs are cached:
* getKeyguardDisabledFeatures()
* hasDeviceOwner()
* getProfileOwnerOrDeviceOwnerSupervisionComponent()
* isOrganizationOwnedDeviceWithManagedProfile()
* getDeviceOwnerOrganizationName()
* getOrganizationNameForUser()
* isNetworkLoggingEnabled()
The caches use a shared key which means that all are invalidated at
the same time. This is slightly less efficient than API-specific
invalidation but it greatly simplifies the invalidation logic in the
server. The cost of invalidating all caches at the same time is small
if invalidation happens infrequently (less than one an hour, on
average).
The test classes are modified to disable caches in the local process.
