This PR adds pass-through, single encryption at gateway and double encryption support (gateway encryption with pass through of SSE headers to backend). If KMS is set up (either with Vault as KMS or using MINIO_SSE_MASTER_KEY),gateway will automatically perform single encryption. If MINIO_GATEWAY_SSE is set up in addition to Vault KMS, double encryption is performed.When neither KMS nor MINIO_GATEWAY_SSE is set, do a pass through to backend. When double encryption is specified, MINIO_GATEWAY_SSE can be set to "C" for SSE-C encryption at gateway and backend, "S3" for SSE-S3 encryption at gateway/backend or both to support more than one option. Fixes #6323, #6696
