Scope

• Add KeyVault::removeKeyAltName as an alias to KeyVault::removeKeyAlternateName
• Add KeyVault::addKeyAltName as an alias to KeyVault::addKeyAlternateName
• Add KeyVault::createDataKey as an alias to KeyVault::createKey

Background & Motivation
addKeyAltName and removeKeyAltName is added to the driver ClientEncryption API in DRIVERS-2017.

Part of the motivation of DRIVERS-2017 is parity with mongosh API. The name addKeyAltName / removeKeyAltName was chosen over addKeyAlternateName / removeKeyAlternateName to be consistent with getKeyByAltName.
