When a provider is registered globally, its
ColumnEncryptionKeyCacheTtlproperty should be set to zero. Before decrypting with a global provider, the property will again be set to zero. Any CEK caching implementation should check this value before caching CEKs and not cache if the value is zero. A globally registered provider should only use the global CEK cache in the driver.
