Description

The new logger class is responsible for a number of environment variables and requires a fair amount of setup before implementing logging. The SeverityLevel enum and environment options described below can be found here.

Acceptance Criteria

• Implement the SeverityLevel enum
• Add method placeholder for each of the severity loggers
• Handle parsing the environment options
• Handle client option parsing and logger instantiation.
• Logger has a hardcoded list of the BSON documents data types that should be converted to EJSON

Testing

Aside from testing the acceptance criteria listed above, test that:

• the MongoClient:
  • will have a valid logger prop if logging is enabled through the environment variables
• the logger:
  • can set the severity level on a per-component bases
  • treats invalid values of the SeverityLevel enum as not set
  • noops when it's disabled
