SingularityNET Daemon v5.1.4

PR: #586

Description:

• new parameter in the config free_calls_users : you can select a specific number of free calls for a specific userID. Example in readme
• a new logger (zap) in the entire project (for logging operations, a performance increase of more than 1000%, memory allocation is 10+ times less compared to the old logger)
• now logs can be written to several sources at once. You can now pass an array in the type field. Examples in logger readme
  • The rotation_time_in_sec and max_age_in_sec parameters have been removed. Instead, they are now max_size_in_mb and max_age_in_days. More detailed.
• logs for the embedded etcd can now be controlled separately using the log_level and log_outputs parameters. Docs for etcdb conf
• the connection_timeout and request_timeout parameters are now used (instead of ipfs) if they are explicitly specified in the config in the payment_channel_storage_client section
• the daemon will now output understandable logs if it fails to connect to etcd
• the hooks have been completely redesigned. Now you can send errors via telegram & email. Example in logger readme
• the init command now generates the simplest possible config file
• fixing tests and errors in the daemon documentation
• the log level will be colored in the console if the type field has a value other than file
