feat(test-server): build the Caching CMM - #2190

Conversation
The ESDK for Java's caching CMM (CachingCryptoMaterialsManager) wraps master key providers, not Material Providers Library keyrings, and the MPL has no caching CMM. Build a top-level Caching config as a CachingCryptoMaterialsManager over a local cache, with its TTL, partition, and byte and message limits, and the master key providers equivalent to the wrapped Default CMM's keyring: Raw AES and Raw RSA as JceMasterKey, the AWS KMS (MRK) single and multi keyrings as the KMS master key providers, and Multi as a multi-provider. Other keyrings, grant tokens, and a Caching CMM nested under another CMM are construction failures.
…M decrypts The ESDK's own CMMs take no reproduced encryption context on decrypt. Check it against the decrypted message's encryption context instead of rejecting it.

The Caching CMM wiring is now on that branch (aws/aws-encryption-sdk-java#2190), so the temporary pin to kessplas/esdk-caching is no longer needed.
