Iteration +3

• Add more defaults from xxx
• Adjust default timeout values to best practices
• Dissolve discrete connection parameters, use connection string only
• Check how configuration per environment variables works
• Think about using prometheus.Labels instead of metric prefixes
• Also prepare SQL statement used for reading?
• Refactor metric names

  Generated/dynamic metric names are a sign that you should be using labels instead. -- https://prometheus.io/docs/instrumenting/writing_clientlibs/#metric-names
