Additions and Improvements

• Introduced SecurityModule plugin API. This allows use of a different security module as a plugin to
  provide cryptographic function that can be used by NodeKey (such as sign, ECDHKeyAgreement etc.). KeyPairSecurityModule
  is registered and used by default. The CLI option --security-module=<name> (defaults to localfile) can be used
  to identify the security module plugin name to use instead. #713
• Several testing related changes to improve compatibility with Hive and Retesteth.
  #806 and #845
• Native libraries for secp256k1 and Altbn128 encryption are enabled by default. To disable these libraries use
  --Xsecp256k1-native-enabled=false and --Xaltbn128-native-enabled=false. #775
