A logger based on bunyan for Base App

Config:

Logger provides log output to a console by default. But also it supports additional log streams which can be adjusted by providing an appropiate config object:

• file - send logs to a file.

  file: {
    path: PATH_TO_LOGFILE;
    level: LOG_LEVEL;
    totalSize: MAXIMAL_SIZE_OF_LOG_FILES;
    threshold: LOGFILE_SIZE_THRESHOLD;
  }

• logstash - send files to logstash.

  logstash: {
    port: LOGSTASH_PORT;
    host: LOGSTASH_HOST;
    level: LOG_LEVEL;
  }

• sentry - send errors or messages to Sentry.

  sentry: {
    level: LOG_LEVEL;
    dsn: SENTRY_DSN;
  }

Log levels:

  trace - 10
  debug - 20
  info  - 30
  warn  - 40
  error - 50
